    Modeling generalized stacking faults in Au using the tight-binding potential combined with a simulated annealing method

    The tight-binding potential combined with a simulated annealing method is used to study the generalized stacking fault (GSF) structure and corresponding energy of gold. The potential is chosen to fit band stru...

    Phonon Hall effect in ionic crystals in the presence of static magnetic field

    We study phonon Hall effect (PHE) for ionic crystals in the presence of static magnetic field. Using Green-Kubo formula, we present an exact calculation of thermal conductivity tensor by considering both posi...

    Cumulants of heat transfer across nonlinear quantum systems

    We consider thermal conduction across a general nonlinear phononic junction. Based on two-time observation protocol and the nonequilibrium Green’s function method, heat transfer in steady-state regimes is stu...

    Strong electron–phonon interaction and colossal magnetoresistance in EuTiO3

    At low temperatures, EuTiO3 system has very large resistivities and exhibits colossal magnetoresistance. Based on a first principle calculation and the dynamical mean-field theory for small polaron we have calcu...

    Three-terminal normal-superconductor junction as thermal transistor

    We propose a thermal transistor based on a three-terminal normal-superconductor junction with superconductor terminal acting as the base. The emergence of heat amplification is due to the negative differentia...

    Transport in electron-photon systems

    We review the description and modeling of transport phenomena among the electron systems coupled via scalar or vector photons. It consists of three parts. The first part is about scalar photons, i.e., Coulomb ...
