У оквиру семинара Центра за изучавање комплексних система Института за физику у Београду, у четвртак, 28. јула 2022. године у 14 часова путем Зум платформе, др Владимир Добросављевић (Florida State University / NHMFL, Tallahassee, USA), одржаће предавање:
Disorder-dominated quantum criticality in moiré bilayers
САЖЕТАК:
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.
