摘要：
A numerical propagation scheme based on dual Lanczos transformation theory is introduced for the propagation of quantum mechanical wave functions in coordinate and phase spaces. This method is applied to the numerical propagation of the coherent state moving in the kicked harmonic oscillator potential. We also make comparisons with classical analogs and we make some comments regarding the advantage of working directly in phase space.
