Quantum Metric Induced Phases in Moiré Materials
Ahmed Abouelkomsan, Kang Yang, Emil J. Bergholtz
We show that, quite generally, quantum geometry plays a major role in determining the low-energy physics in strongly correlated lattice models at fractional band fillings. We ident…

Exceptional dynamics of interacting spin liquids
Kang Yang, Daniel Varjas, Emil J. Bergholtz +2
We show that interactions in quantum spin liquids can result in non-Hermitian phenomenology that differs qualitatively from mean-field expectations. We demonstrate this in two prom…
