有限格点一维分子晶体系统的极化子

Polaron of one-dimensional molecular crystals in finite lattice

本文从量子化的Holstein模型出发,将系统的基态试探波函数取作相干态,由能量极小原理,利用模拟退火法,计算系统的基态能量、晶格位移.

This paper set out from Holstein model of the quantization by means of the method of coherent expansion, based on the energy minimum principle and simulated annealing method, we get the ground energy and the lattice displacement in finite lattice situations.
