The transient dynamics of the eigenstates and coherent states released from a square quantum billiard is analytically and numerically investigated. It is experimentally verified that this transient dynamic can be analogously observed with the free-space propagation of the lasing modes emitted from the laterally confined, vertically emitted cavities. Furthermore, we exploit a chaotically shaped cavity to originally demonstrate the diffraction-in-time characteristics of the chaotic wave functions. It is found that the transient patterns of chaotic wave functions exhibit a striking feature of random branching behavior with the appearance of intricate interference fringes.
对从方形量子台球中释放的本征态和相干态的瞬态动力学进行了分析和数值研究。实验证实，这种瞬态动力学可以通过横向受限、垂直发射腔发射的激光模式在自由空间中的传播类似地观察到。此外，我们利用一个形状混沌的腔来首次展示混沌波函数的时间衍射特性。发现混沌波函数的瞬态图案呈现出具有复杂干涉条纹的随机分支行为这一显著特征。
