Anomalous kinetics and transport from 1D self--consistent mode--coupling theory

, 2006
We study the dynamics of long-wavelength fluctuations in one-dimensional (1D) many-particle systems as described by self-consistent mode-coupling theory.

Macroscopic thermal properties of quasi-inear cellular medium on example of the liver tissue

Computer Assisted Methods in Engineering and Science, 2017
There are two main topics of this research: (i) one topic considers overall properties of a nonlinear cellular composite, treated as a model of the liver tissue, and (ii) the other topic concerns the propagation of heat in the nonlinear medium described

Nonlinear conductivity and breakdown strength characteristics of silicon carbide and hexagonal boron nitride co-doped epoxy resin composites

AIP Advances, 2020
In this study, the method of co-doping semi-conductor silicon carbide (SiC) and insulating inorganic phase hexagonal boron nitride (h-BN) in epoxy resin (EP) composites has been proposed for considering both the nonlinear conductivity and the breakdown ...

Fluctuation conductivity in superconductors in strong electric fields

, 2001
We study the effect of a strong electric field on the fluctuation conductivity within the time-dependent Ginzburg-Landau theory for the case of arbitrary dimension.

Excessive noise as a test for many-body localization [PDF]

, 2019
Recent experimental reports suggested the existence of a finite-temperature insulator in the vicinity of the superconductor-insulator transition. The rapid decay of conductivity over a narrow temperature range was theoretically linked to both a finite ...

Nonlinear Conductivity in Graphene

, 2015
We consider the tight-binding approximation for the description of energy bands of graphene, together with the standard Boltzmann's transport equation and constant relaxation time, an expression for the conductivity was obtained. We predicted strong nonlinear effects in graphene which may be useful for high frequency generation.

Nonlinear conductance of quantum point contacts

Physical Review B, 1989
The conductance of ballistic quantum constrictions in a two-dimensional electron gas has been studied experimentally as a function of the applied voltage. Large nonlinearities are found in the current-voltage characteristics. We give a simple model, which explains the main features of the nonlinear conductance. Breakdown of the conductance quantization
