Nonlinear optical responses of semiconducting graphene nanoribbons: Strong constraint from a hidden symmetry

Jiawei Ruan, Weichen Tang, Yang-Hao Chan +3

Nonlinear optical (NLO) responses are powerful tools for probing material structures, as they are highly sensitive to spatial symmetries. For instance, it is well known that having…

Diagrammatic approach to excitonic effects on nonlinear optical response

Yu-Tzu Chang, Yang-Hao Chan

Optical responses of atomically thin 2D materials are greatly influenced by electron-hole interactions. It is by far established that exciton signatures can be well-identified in t…
