Description
The anharmonic electron-phonon problem is solved in the infinite-dimensional limit using quantum Monte Carlo simulation. Charge-density-wave order is seen to remain at half filling even though the anharmonicity removes the particle-hole symmetry of the model. Superconductivity is strongly favored away from half filling but the anharmonicity does not enhance transition temperatures over the maximal values found in the harmonic limit. copyright 1996 The American Physical Society
