Shaojun LIU , Xiaobo WEI , Zhaodou CHEN , Jun CAI , Benkun MA

材料科学技术（英文）

In this paper, we deduce the analytical form of many-body interatomic potentials based on the Green’s function in tight-binding representation. The many-body potentials are expressed as the functions of the hopping integrals, which are the physical origin of cohesion of atoms. For the simple case of...
