You are cordially invited to the SCL online seminar of the Center for the Study of Complex Systems, which will be held on Thursday, 28 July 2022 at 14:00 on Zoom. The talk entitled

Disorder-dominated quantum criticality in moiré bilayers

will be given by Dr. Vladimir Dobrosavljević (Florida State University and NHMFL, Tallahassee, USA). Abstract of the talk:

Moiré bilayer materials have recently attracted much attention following the discovery of various correlated insulating states at specific band fillings. Here we discuss the metal-insulator transitions (MITs) that have been observed in the same devices, but at fillings far from the strongly correlated regime dominated by Mott-like physics, displaying many similarities to other examples of disorder-dominated MITs. We propose a minimal theoretical model describing the interplay of interactions and disorder, which is able to capture most experimental trends observed on several devices.
