Excitation probability and effective temperature in the stationary regime of conductivity for Coulomb Glasses

open access: yesOpen Physics, 2017
In this paper, we shall illustrate the numerical calculation of the effective temperature in Coulomb glasses by excitation probability provided that the system has been placed in a stationary state after applying a strong electric field.

Monotonicity and enclosure methods for the p-Laplace equation [PDF]

open access: yes, 2017
We show that the convex hull of a monotone perturbation of a homogeneous background conductivity in the $p$-conductivity equation is determined by knowledge of the nonlinear Dirichlet-Neumann operator.

Simple holographic model of nonlinear conductivity [PDF]

open access: yesPhysical Review D, 2013
We present a simple analytic gravitational solution which describes the holographic dual of a (2+1)-dimensional conductor which goes beyond the usual linear response. In particular it includes Joule heating. We find that the nonlinear frequency-dependent conductivity is a constant. Surprisingly, the pressure remains isotropic. We also apply an electric

Nonlinear electric transport in odd-parity magnetic multipole systems: Application to Mn-based compounds

open access: yesPhysical Review Research, 2020
Violation of parity symmetry gives rise to various physical phenomena such as nonlinear transport and cross-correlated responses. In particular, the nonlinear conductivity has been attracting a lot of attentions in spin-orbit coupled semiconductors ...
