Quantum spin Hall insulator on the honeycomb lattice induced by ferromagnetic exchange interaction
Ye-Un An, Song-Jin O, Kwang-Il Ryom +1
We study the many-body instabilities of correlated electrons on the half-filled honeycomb lattice with enhanced exchange coupling. The system is described by an extended Hubbard mo…

A calculation scheme for spectral densities of strongly correlated electron systems using exact diagonalization of dynamical mean field theory
Song-Jin O, Hak-Chol Pak, Kwang-Il Ryom +1
A new approach for calculating spectral density functions of strongly correlated electron systems is proposed within the exact diagonalization method of dynamical mean-field theory…
