About The Speaker

Dr. Yidan Wang received her Ph.D. in Physics from the University of Maryland, where she was mentored by Professors Alexey Gorshkov and Michael Gullans. She is now a Postdoctoral Researcher at Harvard University, working under the guidance of Prof. Susanne Yelin. Dr. Wang's research lies at the intersection of quantum optics, atomic physics, and condensed matter physics. She possesses a keen interest in uncovering universal phenomena that span diverse physical models and is enthusiastic about identifying novel platforms suitable for quantum information technologies. Her current work includes developing the theoretical frameworks for multi-excitation scattering in atomic arrays, exploring universal scattering phenomenon associated with flat bands, probing prethermal behaviors in dynamical phase transitions and exploring the potentials of 2D materials for quantum computing.

Event Details

In free space, the coupling between photons and single atoms is notably weak. However, recent research indicates that by organizing atoms within subwavelength lattice spacings, we can enhance and regulate the interactions between free-space photons and atomic structures. Such configurations lead to collective atomic excitations characterized by exceptionally prolonged lifetimes, known as subradiant states, which hold promise for quantum information tasks. Harnessing the full potential of these systems demands a deep understanding of manipulating multiple excitations, both photonic and atomic, especially when atomic nonlinearities come into play. In this talk, we develop a scattering formalism for multiple excitations in atomic arrays and spotlight the universal behavior near the band edges. Furthermore, we will delve into how the divergent density of states instigates distinct universal scattering phenomena in various physical systems beyond just atomic arrays.
