Pseudogap in high-temperature superconductors from realistic Fröhlich and Coulomb interactions
G. Sica, J. H. Samson, A. S. Alexandrov
It has been recently shown that the competition between unscreened Coulomb and Fröhlich electron-phonon interactions can be described in terms of a short-range spin exchange …
Superlight small bipolarons from realistic long-range Coulomb and Fröhlich interactions
A. S. Alexandrov, J. H. Samson, G. Sica
We report analytical and numerical results on the two-particle states of the polaronic t-Jp model derived recently with realistic Coulomb and electron-phonon (Frohlich) interaction…
Superconductivity in a Hubbard-Froehlich Model and in cuprates
T. M. Hardy, J. P. Hague, J. H. Samson +1
Using the variational Monte-Carlo method we find that a relatively weak long-range electron-phonon interaction induces a d-wave superconducting state of doped Mott-Hubbard insulato…
Time discretization of functional integrals
J. H. Samson
Numerical evaluation of functional integrals usually involves a finite (L-slice) discretization of the imaginary-time axis. In the auxiliary-field method, the L-slice approximant t…
