Excitonic fractional quantum Hall hierarchy in Moiré heterostructures

Abstract:

We consider fractional quantum Hall states in systems where two flat Chern number C=±1 bands are labeled by an approximately conserved 'valley' index and interchanged by time reversal symmetry. At filling factor ν = 1 this setting admits an unusual hierarchy of correlated phases of excitons, neutral particle-hole pair excitations of a fully valley-polarized 'orbital ferromagnet’ parent state where all electrons occupy a single valley. Excitons experience an effective magnetic field due to the...
