Condensed Matter Seminar: Studying Coulomb Correlation and Thermodynamic Properties of Graphene Moiré Structures [Date Changed from 22 September, 2021 to 24 September, 2021 ]
Speaker Jia Leo Li, Brown University
Date 24 September 2021 (Friday)
Time 10:00 - 11:30
Venue Zoom (online)

Graphene moiré structures provide a paradigm system to study correlated physics and superconductivity in the 2D limit. A simple twist between graphene layers gives rise to a unique energy band structure, where strong Coulomb correlation unlocks a rich landscape of quantum ground states such as correlation-driven insulators, superconductivity, and ferromagnetism. Here I will show results from recent experiments which are designed to directly study the role of Coulomb correlation and extract thermodynamic properties of the moiré flatband. I will discuss the implications of these findings on our understandings of graphene moiré systems.
