带温度分布的声弹性波能级动力学实验研究

Experimental Investigation of Energy Level Dynamics of Elastic Wave with Temperature Distribution

利用声弹性波在振荡固体中传播时的性质,采用实验模拟的方法,构造了一个量子混沌体系.通过改变该体系中的一个参量——温度,研究了量子系统中的混沌属性.文中的信号处理采用了过滤对角化方法,对实验结果进行的能谱统计学研究满足了随机矩阵理论的预测.

By using the characteristic of acoustic elastic wave which transmit in vibrating solid and experimental simulation method, a quantum chaos is founded. Through changing one parameter of the system i.e. temperature, we investigate the characteristic of chaos in quantum system. In order to obtain more information of this system, a filter-diagonalization method is applied to analyze signal. The level spectral statistics about this experiment satisfies the prediction of random matrix theory.
