去年人们认识到经典的声学系统可用来研究凝聚态物理的两个前沿领域,其原因是声学系统的机械波和量子系统的电子波满足同样的波动方程。因此可以建造模拟凝聚态系统显著特征的宏观声学系统,从而直接测量本征值、本征函数和其他性质。这些测量在凝聚态系统中即使不是不可能的,也是非常困难的。目前正在研究的是安德尔孙定域的非弹性效应和准晶体的一些性质。 安德尔孙定域是本征函数中的指数形定域。是由一个随机位势中波的长矩离相位相干引起的。凝聚态物理中的一个难题是处理无序的一维导线中的电子波,它牵涉到电子和声子的非弹性散射,后者能产生定
Last year, people realized that the classical acoustic system can be used to study the two frontier fields of condensed matter physics. The reason is that the acoustic waves of the acoustic system and the electronic waves of the quantum system satisfy the same wave equation. It is therefore possible to construct macroscopic acoustic systems that simulate the salient features of condensed matter systems to directly measure eigenvalues, eigenfunctions, and other properties. These measurements are very difficult, if not impossible, in condensed matter systems. Currently under study are the inelastic effects of Andelson domains and some properties of quasicrystals. Andelson domain is an exponential domain in the eigenfunction. Is caused by the phase coherence of a long moment of the mid-wave of a random potential. One of the problems in condensed matter physics is the handling of electrical waves in unordered one-dimensional conductors, which involves the inelastic scattering of electrons and phonons, which can generate
