DESCRIPTION:"Topological Chiral Superconductivity in the Hofstadter-Hubbar
 d Models"\n\nMoir`e materials provide exciting platforms for studying the
  interplay of strong electronic correlation and large magnetic flux effec
 ts. In this talk\, I will report our recent progress on identifying uncon
 ventional topological superconductivity for the doped Hofstadter-Hubbard 
 models.\n\nBased on large-scale density matrix renormalization group and 
 tensor network simulations\, we demonstrate strong evidence for a robust 
 chiral superconducting (SC) phase with dominant power-law pairing correla
 tions for finite cylinders\, nonzero pairing orders for infinite 2D syste
 ms\, and a quantized topological Chern number. The SC phase emerges at ve
 ry weak interaction and grows stronger at intermediate interaction streng
 ths (U) for a wide range of hole doping. We also discuss the possible dis
 tinct nature of the normal state in different U regimes. Our work provide
 s theoretical predictions for the emergence of topological superconductiv
 ity from doping topological Chern bands or magnetic flux induced chiral s
 pin liquid states of Moir`e materials.\n\nhttp://next-to-u.app/events/8a3
