量子台球中的干涉共振

Interfering resonances in a quantum billiard

E. Persson, K. Pichugin, I. Rotter, P. Seba

摘要:

本文提出了一种数值计算与波导相连的二维台球中共振态的位置、宽度和波函数的方法。对于矩形台球,我们研究了与其他谐振杆分开的三个谐振杆的动力学。作为一个函数的波导和台球之间的耦合强度增加的两个国家成为陷阱,而第三个的宽度继续增加所有的耦合强度。谐振极点的这种行为反映在可以通过实验研究的时间延迟函数中。

英文摘要:

We present a method for numerically obtaining the positions, widths and wavefunctions of resonance states in a two dimensional billiard connected to a waveguide. For a rectangular billiard, we study the dynamics of three resonance poles lying separated from the other ones. As a function of increasing coupling strength between the waveguide and the billiard two of the states become trapped while the width of the third one continues to increase for all coupling strengths. This behavior of the resonance poles is reflected in the time delay function which can be studied experimentally.
