Resonances in a single-lead reflection from a disordered medium: -model approach
Yan V. Fyodorov, Mikhail A. Skvortsov, Konstantin S. Tikhonov
Using the framework of supersymmetric non-linear -model we develop a general non-perturbative characterisation of universal features of the density of the imaginary parts…
Sensitivity of (multi)fractal eigenstates to a perturbation of the Hamiltonian
Mikhail A. Skvortsov, Mohsen Amini, Vladimir E. Kravtsov
We study the response of an isolated quantum system governed by the Hamiltonian drawn from the Gaussian Rosenzweig-Porter random matrix ensemble to a perturbation controlled by a s…
Anderson localization on random regular graphs
K. S. Tikhonov, A. D. Mirlin, M. A. Skvortsov
A numerical study of Anderson transition on random regular graphs (RRG) with diagonal disorder is performed. The problem can be described as a tight-binding model on a lattice with…
Crossovers between superconducting symmetry classes
V. A. Koziy, M. A. Skvortsov
We study the average density of states in a small metallic grain coupled to two superconductors with the phase difference , in a magnetic field. The spectrum of the low-energy e…
Correlations of the local density of states in quasi-one-dimensional wires
D. A. Ivanov, P. M. Ostrovsky, M. A. Skvortsov
We report a calculation of the correlation function of the local density of states in a disordered quasi-one-dimensional wire in the unitary symmetry class at a small energy differ…
