Lattice exciton-polaron problem by quantum Monte Carlo simulations
arXiv:0709.3424 · doi:10.1103/PhysRevB.76.184303
Abstract
Exciton-polaron formation in one-dimensional lattice models with short or long-range carrier-phonon interaction is studied by quantum Monte Carlo simulations. Depending on the relative sign of electron and hole-phonon coupling, the exciton-polaron size increases or decreases with increasing interaction strength. Quantum phonon fluctuations determine the (exciton-)polaron size and yield translation-invariant states at all finite couplings.
