Speaker: Ying-Cheng Lai
Affiliation: Arizona State University, USA & University of Aberdeen, UK
Abstract Details: Quantum chaos is referred to the study of quantum manifestations of systems that are chaotic in the classical limit. Most previous research in the field of quantum chaos focused on the non-relativistic quantum regime. Recently the field of relativistic quantum chaos has emerged, due to the tremendous development of research on graphene. Phenomena such as relativistic quantum scarring, chaotic scattering, and tunneling have been explored. The speaker will discuss a number of fundamental issues in relativistic quantum chaos, but from the perspective of quantum control or modulation: how classical chaos can be exploited to harness relativistic quantum behaviors in Dirac fermion and graphene systems? Transport through quantum dot and resonant tunneling will be used as two prototypical examples to illustrate the principle that chaos-based quantum control can be advantageous and experimentally feasible.
