Non-Fermi liquid over extended range at zero temperature without quantum criticality
Tae-Ho Park, Han-Yong Choi
A strange metal state appears in many strongly correlated materials from the cuprates, pnictides, and twisted bilayer graphenes to even bosonic systems. Enormous efforts are being…
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…
Scaling of Coulomb pseudo-potential in s-wave narrow-band superconductors
Tae-Ho Park, Han-Yong Choi
The Coulomb pseudo-potential is extracted by fitting the numerically calculated transition temperature of the Eliashberg-Nambu equation which is extended to incorporate…
