Adiabatic Continuity of the Spinful Quantum Hall States
arXiv:2201.07893 · doi:10.1103/PhysRevB.106.075120
Abstract
By using the extended Hubbard model of anyons, we numerically demonstrate the adiabatic deformation of the spinful quantum Hall (QH) states by transmutation of statistical fluxes. While the ground state is always spin-polarized in a series of integer QH system, the adiabatic continuity between the singlet QH states at and is confirmed. These results are consistent with the composite fermion theory with spin. The many-body Chern number of the ground state multiplet works as an adiabatic invariant and also explains the wild change of the topological degeneracy during the evolution. The generalized Streda formula of spinful systems is justified.
