About me
I am an assistant professor of Physics and Astronomy at Purdue University since August, 2021. I was a postdoc at JQI previously. I got my B.S. degree from Peking University in 2009 and Ph.D. degree from MIT in 2017. I am an experimental AMO physicist, specializing in quantum optics and degenerate quantum gases. I endeavor to explore interactions of new types, on new platforms and in different parameter regimes to advance our understanding of fundamental physics and open up new research areas. My future research will be a continuation of my current and past work, with enhanced level of control. For example, single-site resolution will allow synthetic gauge fields to be applied locally; confining the atoms tightly in 3D optical lattices will enhance the role of interactions between atoms, permitting the study of the interplay between interactions and spin-orbit coupling; subwavelength-spaced arrays of atoms emerge to be a new interface of light-matter interaction, whose properties could be altered by Rydberg excitations; studying Rydberg composites in platforms with precise control of atoms could uncover interesting new states; and so on.
Photons acquire mass and interact with each other by coupling to strongly-interacting atomic states.
Neutral atoms acquire Aharonov-Bohm phase through meticulous laser coupling schemes, thereby emulating fully tunable magnetic fields.
Photon-photon interaction due to Rydberg blockade is accompanied with intrinsic dissipation. We aim at new approaches to solve this problem.
