INTRODUCTION
Welcome to the Quantum Matter Theory Group at APCTP!
The Quantum Matter Theory Group theoretically investigates emergent quantum phenomena in strongly correlated electrons within quantum materials, including van der Waals materials, transition-metal oxides, and strongly correlated metals. We develop effective models for interacting electrons in these materials and analyze their physical properties, such as magnetism and superconductivity, using both analytical and numerical methods.
