Topological edge state with zero Hall conductivity in quasi-one dimensional system

Topological edge state with zero Hall conductivity in quasi-one dimensional system

We explore the structure of the energy spectra of quasi-one dimensional (Q1D) system subjected to spin-density-wave SDW states. The structure of the energy spectra opens energy gaps with Zeeman field. Theses gaps result in plateaus for the Quantum Hall conductivity which is associated with edge stat...
