School and Workshop on Exotic Quantum Phases in Equilibrium and Driven Matter

Administration

Description

The call for applications is now closed.

This School and Workshop explores exotic quantum phases in equilibrium and driven matter, focusing on quantum spin liquids, spin–orbit–coupled materials, experimental probes, and nonequilibrium control via Floquet engineering and ultrafast dynamics.

The program combines pedagogical lectures and research talks covering fractionalization and topological order, experimental probes of quantum spin liquids, candidate materials with strong spin–orbit coupling, and microscopic modeling. It further addresses nonequilibrium phases in driven and synthetic quantum matter, including Floquet engineering, nonlinear spectroscopy, and quantum state preparation, alongside modern theoretical and numerical methods.

Topics

General introduction to quantum spin liquids: fractionalization, topological order, and phase classification
Experimental probes of quantum spin liquids
Candidate quantum materials and their microscopic models
Exotic phases in driven matter Synthetic quantum matter and its nonequilibrium aspects
Theoretical and numerical approaches Quantum state preparation and control
