Statistical analysis of level spacing ratios in pseudo-integrable systems: semi-Poisson insight and beyond
Afshin Akhshani, Małgorzata Białous, Leszek Sirko
We studied the statistical properties of a quantum system in the pseudo-integrable regime through the gap ratios between consecutive energy levels of the scattering spectra. A two-…
Coupled unidirectional chaotic microwave graphs
Omer Farooq, Afshin Akhshani, Michał Ławniczak +2
We investigate experimentally the undirected open microwave network with internal absorption composed of two coupled directed halves, unidirectional networks and $Γ_{-…
Quantum graphs and microwave networks as narrow band filters for quantum and microwave devices
Afshin Akhshani, Małgorzata Białous, Leszek Sirko
We investigate properties of the transmission amplitude of quantum graphs and microwave networks composed of regular polygons such as triangles and squares. We show that for the gr…
Investigation of the enhancement factor in the regime of semi-Poisson statistics in a singular microwave cavity
Małgorzata Białous, Leszek Sirko
We investigated properties of a singular billiard, that is, a quantum billiard which contains a pointlike (zero-range) perturbation. A singular billiard was simulated experimentall…
Distributions of the Wigner reaction matrix for microwave networks with symplectic symmetry in the presence of absorption
Michal Lawniczak, Afshin Akhshani, Omer Farooq +4
We report on experimental studies of the distribution of the reflection coefficients, and the imaginary and real parts of Wigner's reaction (K) matrix employing open microwave netw…
Application of topological resonances in experimental investigation of a Fermi golden rule in microwave networks
Michał Ławniczak, Jiří Lipovský, Małgorzata Białous +1
We investigate experimentally a Fermi golden rule in two-edge and five-edge microwave networks with preserved time reversal invariance. A Fermi golden rule gives rates of decay of…
Missing level statistics in a dissipative microwave resonator with partially violated time-reversal invariance
Malgorzata Bialous, Barbara Dietz, Leszek Sirko
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 t…
The edge switch transformation in microwave networks
Vitalii Yunko, Małgorzata Białous, Leszek Sirko
We investigated the spectra of resonances of four-vertex microwave networks simulating both quantum graphs with preserved and with partially violated time-reversal invariance befor…
