SCL Online Seminar by Vladimir Dobrosavljević
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.
