讲座摘要：Non-Hermitian phenomena such as the non-Hermitian skin effect (NHSE) and exceptional point sensitivity have no Hermitian analogs, and have lately reshaped the way we understand band structures and topology. In this talk, I shall introduce some new ideas that extend the current list of novel non-Hermitian phenomena, such as system-size dependent generalized Brillouin zones (GBZs), as well as GBZs that are fragmented or spatially nonconstant. I shall also highlight how the NHSE can interplay with the geometric defectiveness of exceptional points to lead to novel exceptional bound bands with super volume-law negative entanglement scaling. I will also review how non-Hermitian dynamics have been recently simulated in unitary quantum simulators.
主讲人简介：Assoc. Prof Ching Hua Lee obtained a PhD from Stanford University under the tutelage of Prof Xiaoliang Qi. He joined the National University of Singapore in 2020, and is now heading a team focusing on exploring novel non-Hermitian phenomena, as well as their simulation on classical and quantum platforms. Prof Lee publishes regularly in top scientific journals, and has been cited over 11000 times in the last 5 years.
