Results indicating the important role of the electron–phonon coupling in high-temperature
superconductivity compounds are presented, with emphasis on its implications for angle …

It is generally accepted that the dynamical mean field theory gives a good solution of the
Holstein model, but only in dimensions greater than two. Here, we show that this theory …

A review of experimental and theoretical results on the spectroscopy of high‐temperature
superconductors is presented. The models where hole doped into antiferromagnet interacts …

We generalize the momentum average (MA) approximation to study the properties of models
with gq momentum-dependent electron-phonon coupling. As in the case of the application of …

The behavior of the 1D Holstein polaron is described, with emphasis on lattice coarsening
effects, by distinguishing between adiabatic and nonadiabatic contributions to the local …

The scattering of electrons on impurities with internal degrees of freedom is bound to
produce the signatures of the scatterer's own dynamics and results in nontrivial electronic …

Motivated by the success of the momentum average (MA) approximation for the single-
polaron and bipolaron cases, in this dissertation we pursue the first generalization of this …

The single bipolaron problem is examined in the context of the 1D Holstein-Hubbard model,
emphasizing analogies and differences with respect to the complementary single polaron …

Дискуссия о роли электрон-фононного взаимодействия (ЭФВ) в физике
высокотемпературной сверхпроводимости (ВТСП), которая началась сразу же после …

We review the Dynamical Mean Field Theory of the Holstein Polaron Problem in order to
compute the small polaron Green's functions. The Renormalized Perturbation Expansion …
