Analytical Theory for Anomalous Diffusion in the Anderson Model with Heavy Tails
Elizaveta Safonova, Aleksey Lunkin, Mikhail Feigel'man
We develop an analytical theory of anomalous transport in a noninteracting Anderson model with heavy-tailed hopping amplitudes. The broad distribution of hopping amplitudes gives r…
Multifractal and Glassy Signatures of Non-Ergodic 2D Quantum Dynamics
Aleksey Lunkin, Nicole S. Ticea, Michael T. Solomon +296
The fate of ergodicity and localization in disordered, interacting quantum systems in two spatial dimensions remains an outstanding open problem in non-equilibrium physics. Theoret…
Density of states correlations in Lévy Rosenzweig-Porter model via supersymmetry approach
Elizaveta Safonova, Aleksey Lunkin, Mikhail Feigel' man
We studied global density-of-states correlation function for Lévy-Rosenzweig-Porter random matrix ensemble in the non-ergodic extended phase. Using an extension of Efetov's…
Two-dimensional Coulomb glass as a model for vortex pinning in superconducting films
Igor Poboiko, Mikhail Feigel'man
A glass model of vortex pinning in highly disordered thin superconducting films in magnetic fields at low temperatures is proposed. Strong collective pinning of a vo…
Perturbed Kitaev model: excitation spectrum and long-ranged spin correlations
A. V. Lunkin, K. S. Tikhonov, M. V. Feigel'man
We developed general approach to the calculation of power-law infrared asymptotics of spin-spin correlation functions in the Kitaev honeycomb model with different types of perturba…
Low-energy dynamical response of an Anderson insulator with local attraction
D. A. Ivanov, M. V. Feigel'man
The low-frequency dynamical response of an Anderson insulator is dominated by so-called Mott resonances: hybridization of pairs of states close in energy, but separated spatially.…
Spin correlation functions and quasiparticle decay
Igor Poboiko, Mikhail Feigel'man
We study one-dimensional anisotropic XXZ spin- model with ferromagnetic sign of the coupling and exchange constant , where , and is the coupling…
Ultrasonic attenuation via energy diffusion channel in disordered conductors
A. Shtyk, M. Feigel'man
We predict an existence of an new dissipation channel leading to attenuation of ultrasound in disordered conductors and superconductors with perfect electroneutrality. It is due to…
AC Josephson effect in the long voltage-biased SINIS junction
K. S. Tikhonov, M. V. Feigel'man
Theory of non-stationary coherent effects is developed for superconductor-normal-superconductor (SNS) structures with relatively strong normal scattering on S/N interfaces (interfa…
Electrostatics of Vortices in Type II Superconductors
Gianni Blatter, Mikhail Feigel'man, Vadim Geshkenbein +2
In a type II superconductor the gap variation in the core of a vortex line induces a local charge modulation. Accounting for metallic screening, we determine the line charge of ind…
Vortex Dynamics and the Hall-Anomaly: a Microscopic Analysis
Anne van Otterlo, Mikhail Feigel'man, Vadim Geshkenbein +1
We present a microscopic derivation of the equation of motion for a vortex in a superconductor. A coherent view on vortex dynamics is obtained, in which {\it both} hydrodynamics {\…
