Query: Simulation of the electron-phonon interaction in infinite dimensions   The electron-phonon interaction corresponding to the Holstein model (with
Coulomb repulsion) is simulated in infinite dimensions using a novel quantum
Monte Carlo algorithm. The thermodynamic phase diagram includes commensurate
charge-density-wave phases, incommensurate charge-density-wave phases, and
superconductivity. The crossover from a weak-coupling picture (where pairs both
form and condense at $T_c$) to a strong-coupling picture (where preformed pairs
condense at $T_c$) is illustrated with the onset of a double-well structure in
the effective phonon potential.
