摘要 经典力学进入非线性区域 ,会出现一种随机行为 ,这种行为在量子力学中的表现主要体现在波函数和能级结构方面的特征。本文我们研究了一类边界振动的弹球系统 ,当振动的参数发生变化时 ,系统的准能级的最近邻分布会发生从Poisson分布到GOE(GuassianorthogonalensembleGOE)分布与GUE(Guassianunitaryensemble)分布的转变 ,它们分别对应于可积、时间反演不变的混沌。 Classical chaos means the behavior with time, but for quantum system we mainly talk about the stable states. In this paper, we investigate a system of boundary-oscillating round billiard. When the parameter changes, the quasienergies statistics can lead to Poisson, Guassian orthogonal ensemble(GOE) and Guassian unitary ensemble(GUE), corresponding to integrable, chaotic and non-time-reversible chaotic situations.
