TL;DR: The conductivity sigma(T) of interacting electrons in a low-dimensional disordered system at low temperature T is studied, finding the mechanism of transport in the critical regime is many-particle transitions between distant states in Fock space.

TL;DR: In this paper, the authors developed a theory of magneto-oscillations in the photoconductivity of a two-dimensional electron gas observed in recent experiments, which is governed by a change of the electron distribution function induced by the microwave radiation.

TL;DR: In this paper, the authors theoretically study the quench dynamics for an isolated Heisenberg spin chain with a random on-site magnetic field, which is one of the paradigmatic models of a many-body localization transition.

TL;DR: In this article, a survey of the magnetoresistance oscillations generated by the external forces that drive the electron system out of equilibrium is presented, including microwave radiation-induced resistance oscillations and zero-resistance states.

TL;DR: The frequency-dependent conductivity sigma(xx)(omega) of 2D electrons subjected to a transverse magnetic field and smooth disorder is calculated and the interplay of Landau quantization and disorder scattering gives rise to an oscillatory structure that survives in the high-temperature limit.
