## Dr. Jianwen Jie (postdoctoral researcher)

Dr. Jianwen Jie received his Ph.D. from Renmin University of China, located in Beijing, under the supervision of Dr. Peng Zhang in May 2018. His Ph.D. research focused on few-body problems in ultra cold atomic systems. Jianwen received his B.Sc. in Physics from North China Electric Power University, Baoding, China, where he worked with Profs. Peng Zhang and Zhanyuan Yan. He joined the Blume group in March 2018 as a postdoctoral researcher to work on spinor BECs. In one project, Jianwen investigated the performance of a SU(1,1) interferometer for different classes of initial states. His theoretical work has practical implications for experiments with spinor BECs and he has been collaborating effectively with experimentalists at OU. Jianwen is also interested in non-equilibrium phenomena, such as many-body localization, in cold atom systems.

## Dave Hill (graduate student)

Dave is originally from Michigan’s Upper Peninsula, just shy of the US-Canada border. He did his undergraduate work at Grand Valley State University in Allendale, Michigan, and graduated in 2018 with a B.S. in physics and a minor in mathematics. His undergraduate work involved a photon antibunching project based on the work of Grangier, Roger, and Aspect, and laid the groundwork for an undergraduate quantum optics lab at GVSU. Dave joined the University of Oklahoma in the Fall of 2019, and the Blume group in the Summer of 2020. He is excited to now push further into the world of theoretical AMO physics.

## Jugal Talukdar (graduate student)

Jugal was born in Assam, India – a small scenic state in the remote north-eastern part of the country, which is famous for its tea and greater one-horned rhinoceros. I moved to Pune in the western part of India to pursue higher education and graduated from the Indian Institute of Science Education and Research (IISER), Pune, in 2017 with a BS-MS dual degree. During the undergraduate studies, my research work was focused on the theoretical study of the dynamics of Rydberg excitations coupled to a photonic crystal waveguide. I joined the University of Oklahoma, Norman, in the Fall of 2017 as a graduate student to continue pursuing research in the field of AMO physics.

## AJ Yates (undergraduate student)

AJ was in the International Baccalaureate Program at Fort Dorchester High School. He came to OU in August 2016. AJ holds a National Merit Scholarship and is an Honors student. AJ is planning to graduate from OU with a double major in Physics and Mathematics in 2021. AJ joined the Blume group in early 2018. AJ is studying the intricate behaviors of extremely weakly-bound helium clusters. AJ describes his work as follows: “I use numerical methods to study small Helium-4 clusters. Specifically, I use the variational principle, which states that the expectation value of the energy of any trial wave function is greater than or equal to the ground state energy. I am currently searching for a trial wave function that will recover at least 99% of the exact binding energy of the helium dimer. Once I have found this, I will extend it to the three- and four-body systems to find approximations to their ground and excited states. To find the expectation value of the energy, I use direct integration as well as a variational Monte Carlo code that I developed.”
