Alumni Newsletter - Fall 2019
Greetings from the ChairDr. Justin Sanders
Friends and alumni of the University of South Alabama Physics Department:
It is with great pleasure that we send to you our newsletter for 2018-2019. We have not had a newsletter for several years, so we have many exciting developments to relate. We hope that this newsletter will be one of several ways we will use in the future to keep in contact with our community of former students and faculty. If you would like to help us stay in contact with you, please send us complete updated information.
One of the developments in recent years is that I have become the Department Chair. Dr. S. L. Varghese retired at the end of 2014 after twenty-one years of leading the department. I am fortunate to be able to follow the path blazed by Dr. Varghese. The department continues to do well in educating the next generation of physicians, engineers, scientists, and especially physicists. We are also keeping active in research despite the poor environment for external funding in basic research.
We hope you enjoy learning what we have been up to this past year, and we ask that you will contact us and tell us what you have been up to as well.
Justin M. Sanders
Associate Professor, Department Chair
New Faculty HighlightDr. Arjun Dahal
The department welcomed a new faculty member in August 2018. Dr. Arjun Dahal graduated
from the University of South Florida with a Ph.D. in Applied Physics. He then completed
a Postdoctoral Research Assistantship at Pacific Northwest National Laboratory in
Richland, Washington where he investigated physical and chemical processes governing
the thermal and photo induced reactivity of adsorbed molecules on RuO2 and TiO2. His
current research interests lie in the field of nanotechnology, particularly synthesizing
metal oxide nanoparticles and measuring the properties as a function of their stoichiometry,
crystallinity, thermal stability, interface charge transfer, band gap energy, and
photocatalytic activity. His research goal is to develop novel photocatalyst materials
and improve the photocatalytic efficiency under visible light illumination. Dr. Dahal
is very excited to begin working with undergraduate students in the lab.Dr. Dahal moved here with his wife, Santosh, and two sons, Ashwin and Ayush. We are
very excited to have Dr. Dahal on board and look forward to seeing his research unfold!
Dr. Frank鈥檚 search for magnetic monopoles and other exotic particles with the NOvA
experiment continues with strong contributions from our majors. Josh Robbins presented
a poster at the 2018 SURF Symposium about his summer鈥檚 research work on very slow
monopoles. Hayden Britt and Mitchell Greene gave talks at the 28th Annual Mini-Conference
at USM Gulf Park. Hayden gave a talk on the fundamental particles and Mitchell introduced
the audience to cosmic rays. Mitchell, who is also an ALSAMP scholar, presented this
same work at the 2019 ALSAMP Conference. The summer continued to be busy for Hayden,
Mitchell, and Paul White who assisted in running shifts in our very own 91短视频 ROC (Remote
Operations Center) in the basement and work on the monopole analysis. Mitchell was
funded by a partial SURF fellowship to investigate the effects of cosmic rays on the
monopole analysis. Hayden was funded by a partial SURF/Helminger fellowship to calculate
the deflection of magnetic monopoles due to the Earth鈥檚 magnetic field. Paul was funded
by a Helminger fellowship to investigate the effects of high energy activity in the
NOvA detector. The group is grateful for the University鈥檚 and the Department鈥檚 generous
support to enable all of these research projects.
Research with Dr. Jianing Han
Dr. Han's research focus is on atom-atom interactions with particular emphasis on atom-atom repulsion, such as van der Waals repulsion. In 2018-2019 academic year, physics majors Juliet and Morgan worked her my lab and submitted research results on electric field excitation suppression [1] on arXiv and submitted the article for publication. Juliet was supported by Helminger fellowship. In addition, Juliet and Morgan worked on a narrow-band laser system [2]. Moreover, Dr. Han鈥檚 lab achieved cold atoms below 1 Kelvin trapped in magneto-optical trap (MOT). This is the first MOT in the state of Alabama. The laboratory group posted their results on arXiv in Dec. 2018 and submitted the results for publication [2]. Undergraduate students involved in this research are Lindsay Hutcherson, Gayatri Deshmukh, Morgan Umstead, Andy Hu, Young Lee, and Juliet Mitchell. Lindsay is now a graduate student at Kansas State University, and she was supported by Helminger fellowship. Gayatri and Morgan were supported by an external grant from the Army Research Office (ARO). Andy was supported by UCUR fellowship from the University of South Alabama, and he is now in a graduate program. Young completed his thesis on 鈥淭he preliminary work on macroscopic molecules of 87Rb in an ultracold Rydberg gas.鈥�

Out of 650+ applicants, Sabrina de Jong, was selected to intern for the Harvard School
of Engineering and Applied Sciences (SEAS) REU program during Summer 2019. She was
mentored by Dr. Ariel Amir under post-doc, Ethan Levien, in the field of Biophysics.
She worked on using stochastic simulations to get a better understanding of how bacterial
growth rates evolve in a changing environment. Their hope is that these research efforts
will inspire the development of better techniques for administering antibiotic treatments.
Sabrina says that her experience was 鈥渋ncredible鈥� and she 鈥渓earned a lot of new things.鈥�
91短视频 Physics Graduate, Melissa Bierschenk, recently received her Master鈥檚 in Physics
from the University of Minnesota Duluth. Melissa returned to the 91短视频 Physics Department
as a guest speaker for a summer colloquium on August 2, 2019. She presented her graduate
research material which is heavily grounded in the peaked interest of gravitational
wave astronomy as a result of the first detection of gravitational waves in 2015.
Although detectors like the Laser Interferometer Gravitational-wave Observatory (LIGO)
can observe gravitational wave events, it is important to accumulate a template bank
of realistic waveforms produced by systems with varying parameters. An important part
of the waveform is the inspiral. Melissa used Post-Newtonian approximations and considering
physics such as spin and eccentricity to model the inspiral waveform. Additionally,
she created visual virtual representations of the trajectories of two bodies as they
spiral into each other, and how those parameters change over time. During the colloquium
to students and faculty, Melissa discussed how she solved Post-Newtonian mechanics
for quasicircular and eccentric orbits, how she used Python to create the corresponding
waveforms, and the process of visualizing the trajectories and gravitational waves
and display the appropriate animations.
A highlight of the fall semester is Tuesday Evening Physics! Dr. Godang was the main organizer of this event which includes hosting local high school students for weekly presentations by our faculty. In 2018, we had a total of 55 students from 5 high schools attend!
25th Annual Physics Teacher/Student Workshop
The Annual Physics Teacher/Student Workshop is still going strong! This year we reached a 25 year milestone of hosting this workshop. The faculty work together each spring to host surrounding high school physics teachers and students on campus to explore the Physics Department. The visiting students are selected by their teachers and are considered the top performers in their high school physics courses. Students engaged in hands-on experiments, research laboratory tours, and physics demonstrations. Teachers always enjoy getting out of the classroom for a day of research lectures (and free lunch) with their best students! We hosted a total of 10 teachers and 24 students from coastal Alabama, Mississippi, and Florida this year.
