DESCRIPTION:Presented by: Liang Fu\, Massachusetts Institute of Technology\
 n\nAbstract: The emergence of quasiparticles with fractional charge and fra
 ctional statistics is an essential feature of fractional quantum Hall state
 s\, which occur in two-dimensional electron gas under a strong magnetic fie
 ld. An interesting question is whether fractional electron states can form 
 spontaneously in quantum materials without the external magnetic field. I w
 ill describe theoretical ideas for realizing the fractional quantum Hall ef
 fect at zero magnetic field and highlight the recent observation of this re
 markable phenomenon in moire materials with topological minibands. The pros
 pect of new fractionalized phases without analogs in Landau levels will be 
 also discussed.   \n\nHost: Andrew Lucas
