1 Jun 2006 | Subject: | Superconductivity; Strongly Correlated Electrons | Abstract: | We study a lattice bipolaron on a staggered triangular ladder and triangular and hexagonal lattices with both long-range electron-phonon interaction and strong Coulomb repulsion using a continuous-time quantum Monte-Carlo (CTQMC) technique. We describe a significant extension of the CTQMC algorithm to the Coulomb-Fr"ohlich model with two particles. The algorithm is preceded by an exact integration over phonon degrees of freedom, and as such is extremely efficient. The bipolaron effective mass and bipolaron radius are computed. Lattice bipolarons on such lattices are small but very light in a wide range of parameters, which leads to a high Bose-Einstein condensation temperature. | Source: | arXiv, cond-mat/0606036 | Services: | Forum | Review | PDF | Favorites |
