Sucheta Jawalkar is a post-doctoral associate in the Medium Energy Physics Group working on polarized Compton scattering from 3He.
I was initially drawn to Duke because of its reputation for competitive research in medium energy physics. When I visited, I was exposed to talented researchers in a vibrant university setting. The combination of being affiliated with a cutting-edge photon beam beam facility--TUNL--within walking distance of the university physics building, was very attractive to me. To me -- this seemed like the best of both worlds.
Duke has not only met but exceeded my expectations. The research projects explore physics at the forefront of the field. The fact that I feel like I fit in here has been an added bonus. Spending my post-doctoral years at Duke is broadening the focus of my doctoral work while exploring new avenues of research. I look forward to the opportunities for personal and academic growth and I am excited to be a part of the Duke research community.

Hannah Petersen, Feodor-Lynen Fellow of the Alexander von Humboldt foundation Postdoc in the Nuclear Theory Group
I chose to come to Duke University for my first Postdoc position because the nuclear theory group here is one of the world-leading groups in the field of relativistic heavy ion reactions. The atmosphere of scientific excitement, especially now when the first data for Pb+Pb collisions at the LHC are published, is complemented by a very nice technical infrastructure, e.g. easy access to large computing resources. Since my first visit, I felt really welcome and now that I have been here for almost a year I have experienced great friendliness and support not only within our group, but in the whole department.

The Duke graduate program in physics equips promising students from all over the world with the skills and experience to perform cutting-edge scientific research in physics. Our students go on to become the next generation of leading teachers, scholars, researchers and professionals.
Graduate education at Duke is designed to solidify students' command of the concepts and methods of the discipline through course work and research. Students participate in state-of-the-art research early in their tenure, working closely with a faculty member, to gain personal research experience and a deep understanding of a particular subfield. The education culminates in the completion of a Ph.D. dissertation based on an original piece of research.
Faculty, students and staff within the department maintain a professional environment with a welcoming culture and a truly international climate, so that all students can fully develop their talents and the joy of doing science pervades everyone's experience.

Duke University Physics Department, Science Night 2010
Sep 22 four student volunteers from the Physics Dept’s Outreach Group joined the Chemistry Dept’s Outreach Group for “An Evening of Science” in front of the French Science Building. Using demonstrations, the students explained two topics they learned in mechanics, Newton’s 3rd Law and Waves.
The image here is of a Ruben’s Tube. The pipe has a speaker inserted in one end and the other end plugged. There is a line of small holes drilled along the top and a gas valve on the front – basically a long grill with a speaker in one end. (The Outreach group can cook hot dogs, too!) After turning on the gas and lighting, an amplified function generator sends a sine wave to the speaker at one of the tube’s resonant frequencies. The flame heights will vary according to the sound pressure level at each hole thus the standing wave in flames.
Profs. Calvin Howell, Roxanne Springer, and Ying Wu received funding from Duke’s Office of Global and Strategic Programs, Phillips Endowment, in support of the “International Workshop on Fundamental Physics at a Next Generation Compton Gamma-ray Source (HIGS2)” to take place June 3 and 4 at Duke University. About 70 experimentalists and theorists from the international community, including about 20 local students, are expected to attend the workshop to explore opportunities in nuclear astrophysics, hadronic parity violation, and beyond-the-standard-model physics made possible by the HIGS2 facility. The HIGS2 facility would be developed at the Triangle Universities Nuclear Laboratory as a next-generation Compton gamma source providing a beam from 2 to 12 MeV with an intensity more than two orders of magnitude larger than the present High Intensity Gamma Source (HIGS).

In July Prof. Shailesh Chandrasekharan and postdoctoral associate Dr. Anyi Li traveled to Squaw Valley, Lake Tahoe to attend 2011 International Symposium on Lattice Field Theory. It is the biggest annual meeting for all the people who are doing lattice field theory calculations. 350 participants from all over the world have attended this year's conference. Prof. Chandrasekharan and Dr. Li presented their work on the novel developed algorithm which can efficiently simulate the fermionic system at chiral limit. It is believed that the conventional approach would fail at that limit. Their approach has been well received by the audiences and raised lots of interesting questions and discussions. The new algorithm has promising applications on the physics of graphene and unitary fermi gas. They have started implementing the calculations on those problems.

A possible Higgs event registered in the ATLAS Inner Detector which consists of Pixel detector, Silicon detector and TRT. Each dot in the TRT represents a “hit” from a detector sensor called a straw tube as a charged track traverses the detector. The lines represent reconstructed tracks from the hits, and the towers outside the TRT represent the energy deposited in a calorimeter. The four straight lines moving out from the TRT region are muons (m) from the decay of a Higgs boson candidate, namely H0->Z0Z0->m+m-m+m-.

Prof. Haiyan Gao and collaborators from Norfolk State University, North Carolina A&T State University and Mississippi State University have been awarded recently by the National Science Foundation a Major Research Instrumentation (MRI) grant for the construction of a cryogenic, internal hydrogen gas target for a new experiment on a precise measurement of the proton charge radius, a fundamental quantity important for both atomic and nuclear physics.
The recent development of the “proton radius crisis’’ refers to the intriguing fact that the proton charge radius determined from muonic hydrogen Lamb shift with 0.1% precision is about 7 σ smaller than those from electron scattering experiments and from electronic hydrogen Lamb shift measurements. Before one can determine whether the difference is due to new physics or not, new experiments both in lepton (electron and muon) scattering and atomic Lamb shift are crucial. Prof. Gao and collaborators proposed a new experiment at Jefferson Lab on electron-proton scattering using the combined technique of a high-precision electromagnetic calorimeter, an internal hydrogen gas target, and the well-known quantum electrodynamics electron-electron scattering to achieve a sub percent precision in unprecedentedly low momentum transfer squared. The experiment was approved by the Jefferson Lab Program Advisory Committee in June 2012 with the highest scientific rating. The experiment is expected to take data in the fall of 2014. For more details about this experiment, please visit the Medium Energy Physics Group page and see item #5.
