[Zoom Talk] Physics Department - Quantum Optics in Complex Molecules and Two-dimensional Materials
Abstract
Quantum optics deals with the quantum physics of light-matter interactions traditionally in simple (artificial) atomic or molecular systems, which has laid the foundations of and led to the modern quantum information science and technologies. In this presentation, I will talk about my research on exploring quantum optics in complex molecules and two-dimensional materials. In the first part, I will discuss my development of quantum light spectroscopies to elucidate quantum effects (single-photon events and coherent dynamics) in photosynthetic complexes and semiconducting polymers. In the second part, I will speak about my efforts in engineering quantum light-matter interactions (two-photon interference and single-photon emission) in metasurface and layered materials for optical quantum information processing. I will conclude with a brief outlook for future directions in elucidating coherence and entanglement in condensed matter via quantum optics.
Dr. Li received his B.S. in Physics with honor from Nanjing University in Jun. 2013 and his Ph.D. in Applied Science and Technology from UC Berkeley in Dec. 2019 (advisor Prof. Xiang Zhang). Dr. Li’s Ph.D. research was focused on experimental quantum light-matter interactions in a wide range of nanoscale systems including two-dimensional metasurface and van der Waals materials for optical quantum information science and technologies (Nature Photonics 2021, etc.). Currently, Dr. Li is a Postdoc at UC Berkeley Department of Chemistry (working with Prof. Graham R. Fleming and Prof. Birgitta Whaley), where he pioneers the experimental development of new quantum light spectroscopies to study light absorption and energy transfer in natural photosynthesis and quantum effects in complex systems (Nature 2023, etc.).
