The research with the Lie-Algebra method to the multiphotons excitation of biatomic molecular in the intense laser field 用李代数方法研究强激光场中双原子分子的多光子激发
The acoustical branch and optical branch in lattice vibrational spectrum of biatomic chain only result from the cyclic boundary condition. 指出双原子链的晶格振动分为声学支和光学支是由于采用循环边界条件所造成的结果。
