Multifractality and its role in anomalous transport in the disordered XXZ spin-chain
David J. Luitz, Ivan M. Khaymovich, Yevgeny Bar Lev
The disordered XXZ model is a prototype model of the many-body localization transition (MBL). Despite numerous studies of this model, the available numerical evidence of multifract…
Sub-diffusion in the Anderson model on random regular graph
Giuseppe De Tomasi, Soumya Bera, Antonello Scardicchio +1
We study the finite-time dynamics of an initially localized wave-packet in the Anderson model on the random regular graph (RRG). Considering the full probability distribution $Π(x,…
Higgs modes in proximized superconducting systems
V. L. Vadimov, I. M. Khaymovich, A. S. Mel'nikov
The proximity effect in hybrid superconducting - normal metal structures is shown to affect strongly the coherent oscillations of the superconducting order parameter known as t…
Multifractal dimensions for random matrices, chaotic quantum maps, and many-body systems
Arnd Bäcker, Masudul Haque, Ivan M. Khaymovich
Multifractal dimensions allow for characterizing the localization properties of states in complex quantum systems. For ergodic states the finite-size versions of fractal dimensions…
Robustness of delocalization to the inclusion of soft constraints in long-range random models
P. A. Nosov, I. M. Khaymovich
Motivated by the constrained many-body dynamics, the stability of the localization-delocalization properties to the inclusion of the soft constraints is addressed in random matrix…
Electronic structure of mesoscopic superconducting disk: Quasiparticle tunneling between the giant vortex core and disk edge
A. V. Samokhvalov, I. A. Shereshevskii, N. K. Vdovicheva +4
The electronic structure of the giant vortex states in a mesoscopic superconducting disk is studied in a dirty limit using the Usadel approach. The local density of states profiles…
