摘要
对显含时间的可分线性哈密顿系统构造了2阶模方守恒-辛格式和显式辛格式,并计算了1维有限宽无限深势阱中的电子与模拟激光场的相互作用,结果与理论分析一致。为数值研究时间相关外场中的量子系统,特别是强激光与原子相互作用提供了合理和有效的方法。
order norm preserving and symplectic scheme and 2 order explicit symplectic scheme for separable and linear Hamiltonian system including explicitly time are constituted and applied to compute interaction of the simulated laser field with an electron in the finite width and infinite depth potential well,the results are in good agreement with theoretical analysis.
