Abstract

The two-dimensional (2D) moiré superlattices of transition metal dichalcogenides (TMDCs) have emerged as a promising platform to study correlated physics and excitons in 2D. The moiré potential strongly modulates the valley contrasting excitons resulting from enhanced Coulomb interaction. The moiré flatband further reduces the kinetic energy and leads to strongly correlated electrons. In this talk, we will discuss how to use optical spectroscopy to investigate the excitonic physics and strongly correlated physics in TMDC moiré superlattices, as well as strong interactions between excitons and correlated electrons.
