Dynamical mean-field theory of Hubbard-Holstein model at half-filling: Zero temperature metal-insulator and insulator-insulator transitions
Gun Sang Jeon, Tae-Ho Park, Jung Hoon Han +2
We study the Hubbard-Holstein model, which includes both the electron-electron and electron-phonon interactions characterized by and , respectively, employing the dynamical…

Numerical renormalization group study of the symmetric Anderson-Holstein model: phonon and electron spectral functions
Gun Sang Jeon, Tae-Ho Park, Han-Yong Choi
We study the symmetric Anderson-Holstein (AH) model at zero temperature with Wilson's numerical renormalization group (NRG) technique to study the interplay between the electron-el…
