Non-ergodic delocalized phase with Poisson level statistics
Weichen Tang, Ivan M. Khaymovich
Motivated by the many-body localization (MBL) phase in generic interacting disordered quantum systems, we develop a model simulating the same eigenstate structure like in MBL, but…
Localization and fractality in disordered Russian Doll model
Vedant Motamarri, Alexander S. Gorsky, Ivan M. Khaymovich
Motivated by the interplay of Bethe-Ansatz integrability and localization in the Richardson model of superconductivity, we consider a time-reversal symmetry breaking deformation of…
Electron-phonon heat transfer in giant vortex states
A. V. Samokhvalov, I. A. Shereshevskii, N. K. Vdovicheva +3
We examine energy relaxation of non-equilibrium quasiparticles in different vortex configurations in ``dirty'' -wave superconductors. The heat flow from the electronic subsystem…
Statistics of Green's functions on a disordered Cayley tree and the validity of forward scattering approximation
P. A. Nosov, I. M. Khaymovich, A. Kudlis +1
The accuracy of the forward scattering approximation for two-point Green's functions of the Anderson localization model on the Cayley tree is studied. A relationship between the mo…
Dynamical phases in a "multifractal" Rosenzweig-Porter model
I. M. Khaymovich, V. E. Kravtsov
We consider the static and dynamic phases in a Rosenzweig-Porter (RP) random matrix ensemble with the tailed distribution of off-diagonal matrix elements of the form of the large-d…
Emergent fractal phase in energy stratified random models
A. G. Kutlin, I. M. Khaymovich
We study the effects of partial correlations in kinetic hopping terms of long-range disordered random matrix models on their localization properties. We consider a set of models in…
