Quantum Conductivity for Metal-Insulator-Metal Nanostructures

open access: yes, 2013
We present a methodology based on quantum mechanics for assigning quantum conductivity when an ac field is applied across a variable gap between two plasmonic nanoparticles with an insulator sandwiched between them.

Nonlinear ac conductivity of one-dimensional Mott insulators

open access: yes, 2008
We discuss a semiclassical calculation of low energy charge transport in one-dimensional (1d) insulators with a focus on Mott insulators, whose charge degrees of freedom are gapped due to the combination of short range interactions and a periodic lattice

Dynamical electrophotoconductivity in polycrystalline thin films [PDF]

open access: yes
Polycrystalline cadmium sulfide (CdS) films were deposited on lithium niobate (LiNbO3) substrates by vacuum evaporation and annealed to obtain high photosensitivity. The change in photoconductivity of these films due to the penetration of electric fields

Ballistic transport, chiral anomaly and emergence of the neutral electron - hole plasma in graphene

open access: yes, 2010
The process of coherent creation of particle - hole excitations by an electric field in graphene is quantitatively described using a dynamic "first quantized" approach.

Anomalous conductivity, Hall factor, magnetoresistance, and thermopower of accumulation layer in $\text{SrTiO}_3$

open access: yes, 2016
We study the low temperature conductivity of the electron accumulation layer induced by the very strong electric field at the surface of $\text{SrTiO}_3$ sample.

Nonlinear Field Dependence of Electric Conductivity above the Superconducting Transition [PDF]

open access: yesProgress of Theoretical Physics, 1971
The nonlinear field dependence of the so-called anomalous term in the electric conduc­ tivity due to the fluctuation of the superconducting order parameter is studied theoretically. It is found that in the limit of a large electric field E (i.e. E'J:>Ec= y3/D s0(T)312je where c0 (T) =8/n(T-Tc) and D is the diffusion constant), the anomalous term ...

High-frequency dynamical response of Abrikosov vortex lattice in flux-flow region

open access: yes, 2010
The dynamical response of the Abrikosov vortex lattice in the presence of an oscillating driving field is calculated by constructing an analytical solution of the time-dependent Ginzburg-Landau equation. The solution is steady-state, and work done by the

Second law analysis for MHD permeable channel flow with variable electrical conductivity and asymmetric Navier slips

open access: yesOpen Physics, 2014
The inherent irreversibility in a steady hydromagnetic permeable channel flow of a conducting fluid with variable electrical conductivity and asymmetric Navier slip at the channel walls in the presence of induced electric field is theoretically ...

Nonlinear Hall Acceleration and the Quantum Rectification Sum Rule

open access: yes, 2019
Electrons moving in a Bloch band are known to acquire an anomalous Hall velocity proportional to the Berry curvature of the band which is responsible for the intrinsic linear Hall effect in materials with broken time-reversal symmetry.
