TL;DR: In this paper, the authors investigated the possibility of the formation of a bipo-==================bipolaron out of two polarons in a polarizable lattice and found that only for a highly unlikely set of mate-======rial parameters (such as the polarizability of the particles) it is possible to assimilate a bipolaron without having an external force to keep it together.
Abstract: In this thesis we investigate the possibility of the formation of a bipo-
laron out of two polarons in a polarizable lattice. The formation of a
bipolaron in such a lattice is thought to be a possible explanation for high
Tc superconductivity. Based on classical electrostatics the energy of two
mutually interacting polarizable particles is generalized to N interacting
particles. This result has been used to device of a numerical simulation
for the energy of a uniform square lattice and a CuO2 lattice. Through
these calculations it is found that only for a highly unlikely set of mate-
rial parameters (such as the polarizability of the particles) it is possible to
assimilate a bipolaron without having an external force to keep it together.

TL;DR: In this article, it was shown that Cooper pairs are a solution of the bipolaron problem for model Frohlich Hamiltonian and the total energy of a pair was found for the initial two-particle problems.
Abstract: It is shown that Cooper pairs are a solution of the bipolaron problem for model Frohlich Hamiltonian. The total energy of a pair for the initial Frohlich Hamiltonian is found. Differences between the solutions for the model and initial two-particle problems are discussed.

TL;DR: In this paper, Hartree-Fock (HF) adiabatic molecular relaxation and molecular dynamics techniques are employed to investigate the time evolution of solitons, polarons, bipolarons in charge-density-wave (CDW) ground state materials.
