Nonlinear conductivity of a holographic superconductor under constant electric field [PDF]
Physical Review D, 2017 The dynamics of a two-dimensional superconductor under a constant electric field $E$ is studied by using the gauge/gravity correspondence. The pair breaking current induced by $E$ first increases to a peak value and then decreases to a constant value at late time, where the superconducting gap goes to zero, corresponding to a normal conducting phase ...

The effective electrical conductivity of nonlinear laminate composites [PDF]
Quarterly of Applied Mathematics, 1995 This paper studies the effective nonlinear electrical conductivity of sequentially laminated materials in both two and three dimensions. The exact nonlinear conductive behavior is obtained through a variational procedure [1] that expresses the nonlinear properties of the laminate composite in terms of an optimization with respect to the properties of a
