Distribution of the local density of states, reflection coefficient and Wigner delay time in absorbing ergodic systems at the point of chiral symmetry
Yan V. Fyodorov, Alexander Ossipov
Employing the chiral Unitary Ensemble of random matrices we calculate the probability distribution of the local density of states for zero-dimensional ("quantum chaotic") two-subla…

Superconductor-proximity effect in hybrid structures: Fractality versus Chaos
A. Ossipov, Tsampikos Kottos
We study the proximity effect of a superconductor to a normal system with fractal spectrum. We find that there is no gap in the excitation spectrum, even in the case where the unde…

Signatures of Classical Diffusion in Quantum Fluctuations of 2D Chaotic Systems
Tsampikos Kottos, Alexander Ossipov, Theo Geisel
We consider a two-dimensional (2D) generalization of the standard kicked-rotor (KR) and show that it is an excellent model for the study of 2D quantum systems with underlying diffu…
