Phase rigidity and avoided level crossings in the complex energy plane
E. N. Bulgakov, I. Rotter, A. F. Sadreev
We consider the effective Hamiltonian of an open quantum system, its biorthogonal eigenfunctions and define the value that characterizes the phase…

Electric circuit networks equivalent to chaotic quantum billiards
Evgeny N. Bulgakov, Dmitrii N. Maksimov, Almas F. Sadreev
We formulate two types of electric RLC resonance network equivalent to quantum billiards. In the network of inductors grounded by capacitors squared resonant frequencies are eigenv…
