我们分析和数值计算表明,应用程序的外部磁场高度激发的里德伯激子打破系统中的所有反对一对称性。只有考虑直接带隙立方半导体的完整价带结构,激子的哈密顿量才能导致高斯幺正系综的统计,而不需要与其他准粒子(如声子)的相互作用。因此,我们给出了一个空间均匀系统打破所有的反酉对称性的理论证据。
We show analytically and numerically that the application of an external magnetic field to highly excited Rydberg excitons breaks all antiunitary symmetries in the system. Only by considering the complete valence band structure of a direct-band-gap cubic semiconductor, the Hamiltonian of excitons leads to the statistics of a Gaussian unitary ensemble without the need for interactions with other quasiparticles like phonons. Hence, we give theoretical evidence for a spatially homogeneous system breaking all antiunitary symmetries.
