Collective mode across the BCS-BEC crossover in Holstein model
Tae-Ho Park, Han-Yong Choi
We investigate the emergence of the collective mode in the phonon spectra of the superconducting state within the Holstein model by varying the electron-phonon coupling. Using dyna…
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…
The maximal superconductivity in proximity to charge density wave quantum critical point in CuTiSe
Tae-Ho Park, Obinna P. Uzoh, Han-Yong Choi
Superconductivity emerges in -TiSe when its charge density wave (CDW) order is suppressed by Cu intercalation or pressure. Since the CDW state is thought to be an excitonic…
Dynamical effects on superconductivity in BCS-BEC crossover
Tae-Ho Park, Han-Yong Choi
We investigate the dynamical effects of pairing interaction on superconductivity in BCS-BEC crossover by studying the Holstein model at half-filling where the electron-phonon coupl…
Light-induced current in molecular junctions: Local field and non-Markov effects
Boris D. Fainberg, Maxim Sukharev, Tae-Ho Park +1
We consider a two-level system coupled to contacts as a model for charge pump under external laser pulse. The model represents a charge-transfer molecule in a junction, and is a ge…
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…
