Abstract： 

Huang-Rhys model has been proposed by Kun Huang for the Fcolor center in solid in 1950. During past several decades, this model has been widely used in physics, chemistry,biology and many interdisciplinary subjects. In this lecture, we give the detail derivation of this model in the original paper and the related developing until now. We mainly discuss applications of this model on the radiative and non-radiative transitions in spectroscopy andcarriers-transfer and charge-trapping processes in low-dimensional systems.
