Resistance of 2D superconducting films
E. J. König, I. V. Protopopov, A. Levchenko +2
We consider the problem of finite resistance in superconducting films with geometry of a strip of width near zero temperature. The resistance is generated by vortex configu…
Anomalous Hydrodynamics in One Dimensional Electronic Fluid
I. V. Protopopov, R. Samanta, A. D. Mirlin +1
We construct multi-mode viscous hydrodynamics for one dimensional spinless electrons. Depending on the scale, the fluid has six (shortest lengths), four (intermediate, exponentiall…
Topological Flat Bands and Correlated States in Twisted Monolayer-Bilayer Graphene
Louk Rademaker, Ivan Protopopov, Dmitry Abanin
Monolayer graphene placed with a twist on top of AB-stacked bilayer graphene hosts topological flat bands in a wide range of twist angles. The dispersion of these bands and gaps be…
Highlighting superconductivity in an insulator
Alexander Mirlin, Ivan Protopopov
Superconductor-insulator transition is a fascinating quantum phenomenon that reveals a competition between phase order and charge localization. Microwave spectroscopy provides a no…
Plasmon localization and relaxation, and thermal transport in one-dimensional conductors
M. Bard, I. Protopopov, A. Mirlin
We study the localization and decay properties as well as the thermal conductance of one-dimensional plasmons. Our model contains a Luttinger-liquid part with spatially random plas…
Non-Abelian symmetries and disorder: a broad non-ergodic regime and anomalous thermalization
I. V. Protopopov, R. K. Panda, T. Parolini +3
Symmetries play a central role in single-particle localization. Recent research focused on many-body localized (MBL) systems, characterized by new kind of integrability, and by the…
