Welcome to Bo Zhen’s group in the Physics Department at the University of Pennsylvania! Our research focuses on the intersection between condensed matter physics and quantum electrodynamics. More specifically, a few topics we are current working on include: (1) nano-photonics, (2) topological physics, (3) non-Hermitian physics, and (4) their optoelectronic applications. For more details, please visit the corresponding pages under “Research”. We are always excited to have talented and motivated members to join us, so please contact me if you are interested!
