Generalizing the composite fermion theory for fractional Chern insulators
Hao Jin, Junren Shi
We propose a generalized composite fermion (CF) theory for fractional Chern insulators (FCIs) by adapting the quantum mechanics approach of CFs. The theoretical framework naturally…

Non-quasiconvex dispersion of composite fermions and the fermionic Haffnian state in the first-excited Landau level
Hao Jin, Junren Shi
It has long been puzzling that fractional quantum Hall states in the first excited Landau level (1LL) often differ significantly from their counterparts in the lowest Landau level.…

Quantum mechanics of composite fermions
Junren Shi
We establish the quantum mechanics of composite fermions based on the dipole picture initially proposed by Read. It comprises three complimentary components: a wave equation for de…
