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…

Exploring van der Waals cuprate superconductors using a hybrid microwave circuit
Haolin Jin, Giuseppe Serpico, Yejin Lee +10
The advent of two-dimensional van der Waals materials is a frontier of condensed matter physics and quantum devices. However, characterizing such materials remains challenging due…

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.…
