Research
My current research focuses on experiments exploring collective quantum interactions in rubidium-87 atoms. We begin by cooling the atoms in a magneto-optical trap (MOT) using both Doppler and Sisyphus cooling techniques, and then perform studies on collective emission and absorption phenomena.
I initially worked on assembling external cavity diode lasers (ECDLs) and setting up saturation absorption spectroscopy setups for laser frequency stabilization. I then designed and built a low-noise analog lockbox to stabilize the laser locks. Afterward, we assembled the optical setup for the MOT and continuously optimized it to achieve lower temperatures.
In October 2024, we successfully trapped atoms in a far-off-resonant optical trap. By spring 2025, we achieved our first optical lattices, and we are currently working on creating more tightly confined lattices to investigate collective quantum interactions in these systems.
Earlier in the lab, I also worked on a project measuring the whispering gallery modes of a CaF₂ crystal using a 1550 nm laser. Before joining the lab, I engaged in several theoretical projects, including numerically designing a neutral atom-based phase gate, exploring applications of non-transverse modes in optical fibers, and studying chiral quantum walks.
