Multimode vibronic spectra of the Holstein molecular crystal model
Vibronic spectra of the Holstein model for molecular crystals are investigated using the dynamical mean field theory with the additional aid of the multi-mode Brownian oscillator model. The effects of temperature, ...
Bose-fermi mixtures in a three-dimensional optical lattice
Using the dynamical mean-field theory and the Gutzwiller method, we study the Mott transition in Bose–Fermi mixtures confined in a three-dimensional optical lattice and analyze the effect of fermions on the coherence of ...
Global-local ansatz and dynamical coherent potential approximation study of off-diagonal exciton-phonon coupling
We study the generalized Holstein Hamiltonian in the simultaneous presence of diagonal and off-diagonal exciton-phonon couplings using the global-local Ansatz and the dynamical coherent potential approximation (under the ...
