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-…

Families of isospectral and isoscattering quantum graphs
Pavel Kurasov, Omer Farooq, Michał Ławniczak +4
A concept of germ graphs and the M-function formalism are employed to construct large families of isospectral and isoscattering graphs. This approach represents a complete departur…
