摘 要

Non-Hermitian skin effect--the squeezing of eigenstates toward boundaries--is a generic phenomenon in non-Hermitian settings, and the culprit for the breakdown of bulk-boundary correspondence in non-Hermitian topological systems. To restore the bulk-boundary correspondence, a non-Bloch band theory is often invoked, which, remarkably, can also have significant consequences beyond topology. In this talk, I will discuss the impact of these consequences in dynamic processes, based on recent experiments of photonic quantum walks. I will also briefly discuss the potential implementation of related models with cold atoms.

Brief Intro:

Wei Yi received his PhD in Physics at the Univeristy of Michigan in 2007. He then worked at the Institute for Theoretical Physics, University of Innsbruck, as a postdoctoral researcher, before joining the Faculty of Physics at the University of Science and Technology of China in 2010, where he has stayed to this day. Dr. Yi's main research interest includes ultracold atoms, quantum simulation, and strongly correlated systems.
