Cheng-Shun Wang
Abstract
In this paper,the properties of internal excited state of bulk polaron in a polyatomic crystals are studied.The excitation energy of weak-coupling bulk polaron in a polyatomic crystals were calculated by unitary transformation and Huybrechts's methods.The results show that the ground state energy and the excitation energy of bulk polaron may be written as a series of α the coupling constant.
