Recent Advances in Moiré Systems: from Graphene to Transition Metal Dichalcogenides

Workshop | Monday, September 08, 2025 - Friday, September 12, 2025
Directors:
B. Andrei Bernevig (Princeton University )
Rafael Fernandes (University of Illinois Urbana-Champaign)
Rodrigo Pereira (International Institute of Physics - UFRN)
Oskar Vafek (Florida State University)
Venue:
International Institute of Physics, Natal - Rio Grande do Norte, Brazil
 
Application Deadline: May 31, 2025

Overview:
The fields of strongly correlated and topological electronic systems have witnessed remarkable theoretical and experimental advances over the past decade, reshaping the framework with which we describe and understand quantum matter. A large class of systems where concepts from both fields are intimately entangled are the moiré superlattice systems based on twisting graphene and/or monolayer transition metal dichalcogenides (TMDs). Under certain conditions, which can be controlled by the twist angle, pressure, and gate voltage, the long period of the moiré superlattice gives rise to narrow bands.

This conference will bring together experimentalists and theorists working on this exciting research area, focusing on both unresolved challenges as well as recent discoveries in the rapidly growing field of moiré systems, from the correlated insulating phases of twisted bilayer graphene to the recent observation of superconductivity and fractional Chern insulating behavior in twisted homobilayer transition metal dichalcogenides.

Main topics:
- Fractional Chern insulators in moiré systems
- Mechanisms for superconductivity in twisted n-layer graphene and twisted TMDs
- Moiré phonons and phasons
- Microscopic models for correlated electronic behavior in twisted systems
- Topology and quantum metric in flat-band systems
- Novel experimental probes of moiré devices
- Twisted superconductors and twisted quasicrystals
