Missing-level statistics in a dissipative microwave resonator with partially violated time-reversal invariance

We report on the experimental investigation of the fluctuation properties in the resonance frequency spectra of a flat resonator simulating a dissipative quantum billiard subject to partial time-reversal-invariance violation (TIV) which is induced by two magnetized ferrites. The cavity has the shape of a quarter bowtie billiard of which the corresponding classical dynamics is chaotic. Due to dissipation it is impossible to identify a complete list of resonance frequencies. Based on a random-matrix theory approach we derive analytical expressions for statistical measures of short- and long-range correlations in such incomplete spectra interpolating between the cases of preserved time-reversal invariance and complete TIV and demonstrate their applicability to the experimental spectra.

耗散微波谐振器中的缺失级统计,其时间违规不变性部分受到破坏

我们报告了对平面谐振器的共振频谱中的波动特性进行实验研究的结果,该谐振器模拟了由两个磁化铁氧体引起的部分时间不变性违反(TIV)的耗散量子台球。空腔的形状为四分之一领结台球,其相应的经典动力学是混乱的。由于耗散,不可能确定谐振频率的完整列表。基于随机矩阵理论方法,我们导出了在时间不变性和完整TIV情况之间插值的这种不完整光谱中短时和长期相关性的统计量度的分析表达式,并证明了它们在实验光谱中的适用性。
