SYWS: Symposium Quantum 2D-Moiré and Rhombohedral van-der-Waals Systems

SYWS 1: Quantum 2D-Moiré and Rhombohedral van-der-Waals Systems

Donnerstag, 11. September 2025, 10:45–12:45, ZHG008

Recent advancements in the field of 2D-Moiré and rhombohedral van-der-Waals systems have significantly enriched the landscape of quantum materials. These versatile platforms allow the creation and control of flat bands and enable tunable quantum phase diagrams – critical for advancing quantum technologies. The tuning of flat bands, either through precise control of the Moiré angle or by introducing an external electric field, has enabled the discovery of various emergent phenomena such as (fractional) Chern insulators, ultrafast exciton dynamics, and superconductivity. The symposium will showcase complementary experimental and theoretical approaches to uncover and control such complex electronic states in novel van-der-Waals heterostructures.
