From Fractionalization to Chiral Topological Superconductivity in a Flat Chern Band
Daniele Guerci, Ahmed Abouelkomsan, Liang Fu
We show that interacting electrons in a flat Chern band can form, in addition to fractional Chern insulators, a chiral -wave topological superconductor that hosts neutral Majora…

Shining light on collective modes in moiré fractional Chern insulators
Nisarga Paul, Ahmed Abouelkomsan, Aidan Reddy +1
We show that collective excitations and optical responses of moiré fractional Chern insulators (FCIs) drastically differ from those of standard fractional quantum Hall (FQH) states…
