摘要: 我们用存活率(SP)的概念研究了无限方势阱本征态的稳定性,做了理论上的推导,并进行了数值计算,发现基态在外界的扰动下非常稳定,而激发态则非常不稳定,能级越高,越不稳定.

关键词: 存活率(SP), 稳定性, Loschmidt, echo(LE)

Abstract: We use the concept of survival probability to study the stability of the eigenstate in the infinite square well.It is found from theoretical analysis and numerical calculation that the ground state is very stability under the perturbation of the Hamitonian while the exited state is very sensitive to the perturbation of the perturbation of the Hamitonian.

Key words: survival probability(SP), stability, Loschmidt echo(LE)
