Radiative polaritons at JMU

Radiative polaritons are known since their theoretical description by Fuchs and Kliewer in the sixties.  However, the reason why they are radiative was not explained, the existence of the radiation emitted was not proved, and the frequency range of that radiation was never found.  Three undergraduate students at JMU with the help of collaborators at the University of Utah and Howard University have done all this: Anita discovered why radiative polaritons are radiative, and Yosyp discovered the existence of the emitted radiation.  Yosyp and Harkirat found that the "radiated" radiation exists in the microwave to far-infrared frequency range.  For more details see the paper:  A.J. Vincent-Johnson, Y. Schwab, H.S. Mann, M. Francoeur, J.S. Hammonds, and G. Scarel, “Origin of the low frequency radiation emitted by radiative polaritons excited by infrared radiation in planar La2O3 films”.  J. Phys: Condens. Matter 25, 035901 (2013).

Virginia Academy of Science - Undergraduate Research Meeting

On Saturday October 27 2012, the Virginia Academy of Science Fall Undergraduate Research Meeting took place at the Reynolds Community College in Richmond.  The JMU Undergraduate student in Physics Harkirat Mann presented a poster entitled "The origin of fluctuations in the heat and radiation excited Seebeeck effect".  Harkirat and his advisor, Dr. Govanna Scarel, describe an apparatus that will help understanding whether an environment free of humidity and heat variations aids in observing delicate voltage transients.  Harkirat will build the apparatus in the next months, and the results of the research will help him and his group to improve the research on harvesting infrared radiation by transforming it into electricity.

Intruguing non-linear phenomena discovered at JMU!

How is it possible that a voltage signal excited by infrared radiation decays as the excitation source remains on?  Anita Vincent-Johnson, who graduated in physics at JMU on May 2012, found that the strange phenomenon might be due to chaotic transport in a thermoelectric power generator interacting with infrared radiation.  The mystery is not fully unveiled and the team of Dr. Scarel continues the investigations.  The latest news were published today:
A.J. Vincent-Johnson, A.E. Masters, X. Hu, and G. Scarel, “Excitation of radiative polaritons by polarized broadband infrared radiation in thin oxide films deposited by atomic layer deposition”.  J. Vac. Sci. Technol. A vol. 31, 01A111 1-4 (2013).

Why Study Physics?

Why should you study physics? Maybe you want to have a job when you graduate -and- make a lot of money? Perhaps you want to go Medical School? How about Law School? Or maybe Business School? Did you know that acceptance into these very competitive programs is (largely) based on your performance on standardized tests like the MCAT, LSAT, & GMAT? Did you know that Physics majors have the highest scores on these tests? That they have the lowest unemployment rates when they graduate? That they have amongst the highest paying jobs with an undergraduate degree in Physics? Besides, PHYSICS IS FUN! Learn more by watching this short clip, and then learn more about the Physics and Astronomy program at James Madison University

Come learn more about Physics & Astronomy at our OPEN HOUSE this Saturday from 9am to noon! Meet students & faculty, tour our labs, watch really cool physics demos, and learn more about the department, our scholarships, and the process at 10am and 11am in Room 2212 in the Physics & Chemistry building!

The Big Reach of JMU Physics...


With blogs, Facebook, twitter, etc, and even teaching, we can sometimes forget just how far and wide the discussion reaches and just how small our planet becomes. Three recent examples demonstrates clearly just how large the reach is of JMU's Department of Physics & Astronomy.



1. Dr. Giovanna Scarel on WMRA's The Spark!
WMRA, the Valley's local NPR affiliate hosts a weekly show called "The Spark". This show is WMRA's look into "creativity", they "dig into whatever people are passionate about in the WMRA region: sculpture, model railroading, costume-making, poetry, whatever". On Friday, May 11, Dr. Giovanna Scarel was profiled on "The Spark". What is a photon?  Solid state physicist Dr. Giovanna Scarel explains photons and why such tiny things are intriguing. If you missed the interview, you can find the audiocast of it here.



2. Saturday Morning Physics Student Discovers a Pulsar!
For the past two years, Dr. Adriana Banu has organized a 6-week winter enrichment program for area high school students. The idea is to get them exposed to "cutting edge" physics, and to bring some of the excitement of the lab into the classroom for students to witness firsthand. 

Cecilia McGough, a senior at nearby Strasburg High School, participated in the 2nd Saturday Morning Physics program at JMUAfter her SMP experience, Cecilia spent the summer working at the Green Bank Radio Telescope in West Virginia where she became just the 6th high school student to discover a pulsarA pulsar is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation as the star rotates extremely quickly, just as a lighthouse sweeps out a bright patch of light as it rotates. McGough's pulsar has a period of 185.549 milliseconds and is about the size of Washington D.C.!



At the start of the year, much nonsense was spread on the internet about the Mayan calendar coming to an end, and how that portends the end of the world! Recently, JMU invited Dr. Phil Plait (the "Bad Astronomer") to debunk claims like these and others found online that the end-of-the-world is coming this December (more on this soon!). However, prior to his visit, Planetarium Director Shanil Virani wrote his own article for the Planetarium's website. While this was featured in a local newspaper article,  we very surprised to get the email below from a teacher in SOUTH AFRICA that were studying some of these doomsday claims! One of the students in the class actually referred to the Planetarium's 2012 debunking in their discussion and showed the website to her teacher! The email below was sent to Shanil Virani this past summer and is reprinted with permission from the author. 

From: Pauline Smith 
Subject: Excellent Article on JMU Website
Date: July 26, 2012 
To: Shanil Virani
 
I have just had the pleasure of reading your online article on Debunking the 2012 Doomsday Prophecies, and may I say – Bravo!
 
One of my learners brought up the subject of the end of the world in December 2012, and another mentioned your article in refuting her classmate’s assertion that “we’re all going to die before Christmas anyway!”
 
I found the blend of hard science and popular culture an unusual but effective tool to calm the hysteria and ‘talk them out of the trees’.
 
I especially liked your suggestion that the Planetarium be made the beneficiary if an individual is that certain of his or her imminent destruction!
 
Thank you for a well written article, and an unexpected laugh for an otherwise cold and wet Thursday.
 
 
Kind Regards,

7 Minutes of Terror: Mars Curiosity Lands TONIGHT!

On Saturday, November 26 at approximately 10:02AM (EST), Mars Science Laboratory (MSL) lifted off from Cape Canaveral Launch Complex 41 en route to Mars. After more than 8 months in flight, MSL arrives very LATE tonight! The SUV-sized rover it is carrying, called Curiosity, is expected to touchdown on the surface of the Red Planet at 1:31AM (i.e., early Monday morning). After traveling 566 million kilometers, imagine a remote-controlled Cadillac Escalade landing in a dust storm.

This will be no easy feat. In fact, arriving and surviving touchdown would be an enormous scientific and engineering accomplishment. The landing sequence is incredibly risky (see image and 7 Minutes of Terror) and of Mankind's 39 missions to Mars, we've been successful only 15 times. I fully expect very late tonight to be the 16th time we've been successful in landing on Mars but it is important to be aware of the risk of failure and to recognize the extraordinary accomplishment if successful.

Despite the poor odds, we continue to go. Why? Mars Curiosity will open a new opportunity to study the habitable environment of the Red Planet. If you have come to the John C. Wells Planetarium recently, you will have heard me say during my star talk that in my opinion, the greatest discovery in science would be the discovery of life outside of Earth. While NASA's Kepler mission has done an extraordinary job discovering exoplanets, some even in the so-called "habitable zone" where water (should it exist) would be in its liquid form, the best evidence of life outside of Earth may come from within our Solar System, Mars in particular.

Previous missions to Mars has confirmed the hypothesis that Mars had liquid water in its past. But does Mars host life currently? Did it in the past? The answers to these questions have been inconclusive so far. This is where Mars Curiosity comes in. It is landing in Gale Crater, a carefully-chosen landing site after 5 years of analysis. This ~93 mile-wide-crater is an ancient impact basin for which there is very good evidence to suggest an ancient river once flowed through it. It is also a site with mineral-rich terrains and a mountain right in the middle where Curiosity will spend most of its time working to learn if it had an environment where microbes may have thrived.

This story begins tonight! Join me on twitter tonight where I will provide updates and commentary. You can watch NASA TV's feed online if your cable tv carrier does not carry it. Note that once Curiosity lands, it will be 14 minutes for us to receive telemetry that touchdown was successful and another 14 hours to get the first high resolution images that Curiosity will snap from its landing site.

My 2-year old son and I watched the launch on that Saturday morning after Thanksgiving Day and I am going to try to keep him up tonight for this historic landing!

The 2012--2013 Academic year

This year's incoming class is a new department record: 34 freshmen and 2 transfers for a total of 36. In addition, one of the freshmen is our first ever Dingledine scholar,  Devin Buenemeyer. This is a real honor for the department. We are extremely proud of her and delighted that she has chosen physics and our department. The graduating class this year was small (13) but next year's promises to be sizable (20 or more). With the addition of Shanil Virani as our recruiter, we have great expectations. Shanil has many excellent idea and a tremendous amount of energy. Jon Staib has passed the baton with a clear lead for the department and Shanil is ready to run (forgive the Olympics metaphor). Don't be surprised if remarkable things happen.

We have a strong incoming class this year. We have some very excellent students as upperclassmen. We are growing and getting better.

This year we add Keigo Fukumura and Jarrett Lancaster. Elizabeth Jeffery is staying with us for another year or two and searches to fill open positions are going to commence in a month or two. Costel Constantin is moving into a tenure track position. Brian Utter is going on sabbatical in Germany and Scott Paulson is taking the Research Semester in the fall to spend time in Charlottesville. Both are moving their research interests towards biological systems.

The department reached a new high this year in external funding with a total of over $4.77 million. The only tenure track faculty without external funding in the department are the new folks, Costel and Keigo, and they will be funded soon at the rate things are going. Such vigorous research is rare in undergraduate departments and actually not all that common in research institutions We are a young department with only three faculty (Kevin Giovanneti, Chris Hughes and Mark Mattson) hired before 2001.

We are still pushing to open the Madison Radiation Laboratory asap. and proposals are being written to obtain money for experiments there. Discussions with the university administration is continuing.

Every year is better that the last and this year is no exception.

Come visit.

Be part of the amazing PandA@JMU.

Washington Post says there are no science jobs, but...

The Washington Post has an article today about job prospects for scientists. The article, U.S. pushes for more scientists, but the jobs aren’t there, tries to paint a doom and gloom picture of the job prospects for scientists. It points to neuroscience and pharmaceuticals as places that are no longer hiring PhD's and that
it’s questionable whether those youths will be able to find work when they get a PhD. Although jobs in some high-tech areas, especially computer and petroleum engineering, seem to be booming, the market is much tighter for lab-bound scientists — those seeking new discoveries in biology, chemistry and medicine.
Sounds pretty nasty out there, doesn't it? Buried on page two is, however, the key point:
Two groups seem to be doing better than other scientists: physicists and physicians. The unemployment rate among those two groups hovers around 1 to 2 percent, according to surveys from NSF and other groups. Physicists end up working in many technical fields — and some go to Wall Street — while the demand for doctors continues to climb as the U.S. population grows and ages.

Catch that? 1 -2% unemployment for physicists and physicians.  In an economic downturn with overall unemployment of 8.2%? This would be great news in any kind of economy.

So in case you were wondering why an undergraduate degree in physics is the place to start your medical career, this is the reason. Not only is physics a great career choice, it is an ideal "plan B" for charting a path to medical school. What happens if you don't get into medical school? Only good things if you have a physics degree. An undergraduate degree in physics puts you in a place to get a good paying technical job or pursue graduate work for an even higher paying job. And it looks like your chances of finding that good paying job are 98-99%.

Physics. Still the best deal in town.

Don Chodrow Memorial Scholarship Endowment



On behalf of the friends, current and former students and colleagues of Dr. Chodrow, a scholarship in his honor has been created. The Don Chodrow Memorial Scholarship Endowment will provide resources annually for one or more outstanding undergraduates in the Department of Physics and Astronomy.

To be eligible for this scholarship, a student must have a cumulative grade point average of 3.5 or higher and at least four semesters of study. By selecting from among our very best junior and senior physics majors, we honor the tradition of excellence for which Don was such a strong advocate both in and out of the classroom.

To create an endowed fund so that this scholarship is permanent, we must raise at least $25,000 by 2017. You may support this scholarship either by check or by giving on-line. Complete information is found on the web here.

Recognize the difference that Dr. Chodrow made in your life by considering a contribution to this fund. By "paying it forward" you can help us carry on his tradition of student centered education of the highest quality.

Don Chodrow

Physics and Astronomy has lost Don Chodrow to an automobile accident.  On Monday June 18th, Don was involved in a single car accident on I-81.  He was on his way to teach Phys 150 in summer session. He was flown to UVA Medical Center, but never regained consciousness. After organ donation, he was removed from life support on June 20th. One of the bright lights in our department has gone out.

Don was such a big part of our department for the past 32 years that it is impossible to understand what we will be without him. He was always a strong voice for high quality education for all of our students. As the long-time instructor of advanced mechanics (Phys 340), he guided our majors toward understanding physics deeply and broadly. His dedication to teaching is without parallel. He eagerly taught any and every course offered to him.  Don was routinely in front of classes that spanned the spectrum in our department, from GSCI 101 to second-semester quantum mechanics. He was a leader in curriculum development, chairing the Curriculum and Instruction Committee for more than a decade. He guided many students to graduation, successful careers, and graduate school in his role as an academic advisor. Our majors revered him.

His presence also filled the department in a dozen small ways. He was always quick with a laugh or a joke so bad you had to laugh in response.

Don always had a hand on the rudder of the ship that is Physics and Astronomy. We will continue in his absence for he would have it no other way, but without his steady hand our direction is just a bit less well-defined.

We are thankful for all that was gentle and noble in his life. We will miss you, dear friend.




The family asks that no flowers be sent. Donations may be sent to Temple House of Israel, P.O. Box 1412, Staunton, VA 24402, or to the Don Chodrow Memorial Scholarship Endowment. We are creating a scholarship in Don's name to continue his long tradition of putting our student's education first.

The Science enabled by Photon Sources: Local interest in Virginia

On May 16 2012 the Workshop on "The Science enabled by Photon Sources: local interest in Virginia" took place at JMU. Several Faculty members of the Department of Physics and Astronomy were in the Organizing Committee (Dr. Whisnant, Dr. Hughes, and Dr. Scarel). Dr. Hughes, Dr. Utter, Dr. Feitosa, Dr. C. Constantin, and Dr. Scarel were among the presenters. The Workshop gave an ample view of the vast capabilities of photon Sources in various fields of Science. Dr. Ward Plummer (Louisiana State University), one of the keynote speakers, gave a historical picture of the evolution of Photon Science and offered an overview of the possible developments. His talk touched topics related to physics and materials science, in particular related to superconducting materials. The need of photon sources to improve the research in materials science was illustrated in the presentations of various JMU faculty members, who underlined the need for better imaging techniques, and more sensitive tools to perform chemical analysis in soft and hard materials. Dr. Peter Abbamonte (University of Illinois – Urbana Champaign), another keynote speaker, illustrated how the mystery of the lack of a band gap in graphene was solved using high energy photons produced in a storage ring. Other presenters from JMU and from other Universities in Virginia and Washington DC described the power of photon sources in understanding phase transitions in oxides, collective excitations, and the properties of photon themselves. Dr. Stefan Vogt (Argonne National Laboratory and Northwestern University), the third keynote speaker, succeeded in convincing that photon sources offer enormous possibilities in the fields of biology and medicine. A new JMU Chemistry faculty member supported the view. Other presentations illustrated new fascinating mysteries awaiting to be investigated with the powerful photon sources in the fields of environmental sciences, electronics and spintronics, and mentioned the technical challenges associated to the process of data acquisition. A radio interview of Dr. Scarel aired on May 11 2012 can be found at http://wmra.org/post/physicist-giovanna-scarel

Physics weekend affairs again: the CAA Undergraduate Research Conference

The weekend of the April 13th-15th , [Jimmy Corcoran, a junior physics major] had the opportunity to participate at the Colonial Academic Alliance (CAA) Undergraduate Research Conference [at Old Dominion University in Norfolk].  Initially I wasn't sure I was skeptical about whether or not I would enjoy the experience, but I was quickly reassured.  There were events spaced out throughout the entire weekend, enough so that you always knew you were kept in an academic mindset, but not so many that you felt overwhelmed and didn't have enough time to relax.  Everything over the course of the trip went smoothly, both of the keynote speakers were fantastic speakers and were able to captivate the entire audience, regardless of their academic focus; the spacing out of all of the student presentations, and even all of the meals prepared for everybody were fantastic.  Overall I thought it was really a fantastic experience to be around so many people involved in undergraduate research in their respective fields, and also for the opportunity to share the research I've been doing with my peers from the entire CAA.  

Jimmy  was one of the 3 physics majors representing JMU physics and astronomy undergraduate research (out of a total of 10 JMU selected undergraduates): Jimmy the astronomer was accompanied by Ethan Cummings and Thomas Hoke (both juniors) who presented their findings on some novel materials' behavior at this 10th annual CAA conference.   Here are the three of them ( ...musketeers in quest for scientific answers to how the world works):


and here are some details about their presentations, as described in the Madison Scholar
What can we say, they have their own ways of saving the world!
We heard not once that "they were excellent presenters!"

JMU Physics Helping Out

This weekend students from all around JMU worked on service projects throughout the community as part of the "The Big Event", an annual day of community service. JMU Physics students and faculty give back to the Harrisonburg-Rockingham community in many ways all year long. Some by coaching Little League baseball and others by working with kids to learn about science.



For the second year in a row, Dr. Costel Constantin has organized a NanoDays event for the community at the Explore More Discovery Museum in Harrisonburg. With the help of JMU nanoscientists Drs. Brian Augustine, Kyle Gipson, and Chris Hughes, and a team of local school teachers and JMU students, the doors to the museum were opened for free from 1:00-4:00 pm on Sunday, April 15 for nearly 150 visitors to come learn about the amazing things that happen at the scale of one billionth of a meter. The event even got covered by our local TV station. Plans are already underway for next year's event which should happen some weekend in late March or early April of 2013.
