论文摘要
由于声子调节的跳跃引起的极化效应问题，我们制定了一种通用的蒙特卡洛技术，用于在粒子和原子位移的坐标表示中求解它。该方法适用于广泛的模型；唯一的条件是跳跃振幅是标志阳性的。具有相应效率增益的方案的戏剧性简化发生在具有分散声子的模型中。我们的研究阐明了基于线性化位移调制跳跃的“标准”（PEIERLS/SU-SCHRIEFFER-HEEGER）模型所证明的最引人注目的定性和定量效应的性质和普遍性。
Motivated by the problem of polaron effect due to phonon-modulated hopping, we formulate a generic Monte Carlo technique for solving it in the coordinate representation for both the particle and atomic displacements. The method applies to a broad class of models; the only condition is that the hopping amplitude be sign-positive. A dramatic simplification of the scheme, with the corresponding efficiency gain, takes place in models with dispersionless phonons. Our study sheds important light on the nature and universality of the most striking qualitative and quantitative effects demonstrated by the "standard" (Peierls/Su-Schrieffer-Heeger) model based on the linearized displacement-modulated hopping.
