Density-matrix embedding theory study of the one-dimensional Hubbard-Holstein model
Teresa E. Reinhard, Uliana Mordovina, Claudius Hubig +5
We present a density-matrix embedding theory (DMET) study of the one-dimensional Hubbard-Holstein model, which is paradigmatic for the interplay of electron-electron and electron-p…
Systematic construction of density functionals based on matrix product state computations
Michael Lubasch, Johanna I. Fuks, Heiko Appel +3
We propose a systematic procedure for the approximation of density functionals in density functional theory that consists of two parts. First, for the efficient approximation of a…
Many-body Green's function theory for electron-phonon interactions: ground state properties of the Holstein dimer
N. Säkkinen, Y. Peng, H. Appel +1
We study ground-state properties of a two-site, two-electron Holstein model describing two molecules coupled indirectly via electron-phonon interaction by using both exact diagonal…
