Exact expression for Drude conductivity in one-dimension with an arbitrary potential

, 2008
An exact expression for the Drude conductivity in one dimension is derived under the presence of an arbitrary potential. In getting the conductivity the influence of the electric field on the crystal potential is taken into account.

Dyadic Green's Functions and Guided Surface Waves for a Surface Conductivity Model of Graphene

, 2008
An exact solution is obtained for the electromagnetic field due to an electric current in the presence of a surface conductivity model of graphene. The graphene is represented by an infinitesimally-thin, local and isotropic two-sided conductivity surface.

Out-of-plane fluctuation conductivity of layered superconductors in strong electric fields

, 2005
The non-Ohmic effect of a high electric field on the out-of-plane magneto-conductivity of a layered superconductor near the superconducting transition is studied in the frame of the Langevin approach to the time-dependent Ginzburg-Landau equation.

DC-conductivity of a suspension of insulating particles with internal rotation

, 2009
We analyse the consequences of Quincke rotation on the conductivity of a suspension. Quincke rotation refers to the spontaneous rotation of insulating particles dispersed in a slightly conducting liquid and subject to a high DC electric field: above a ...

Decrease of the electric field penetration into the ionosphere due to low conductivity at the near ground atmospheric layer [PDF]

Annales Geophysicae, 2010
It is well known that lithospheric electromagnetic emissions are generated before earthquakes occurrence. In our study, we consider the physical penetration mechanism of the electric field from the Earth's surface, through the atmosphere-ionosphere ...

Clinical Usage of Tissue Electrical Conductivity during the Electroporation: An Essential and Useful Factor

Frontiers in Biomedical Technologies, 2021
Electric field intensity at each point is responsible for pore creation in the cell membrane during the electroporation process. These pores can increase the tissue electrical conductivity in the electroporation.

Non linear excess conductivity of Bi$_2$Sr$_2$Ca$_{n-1}$Cu$_n$O$_{2n+4+x}$ (n = 1,2), thin films

, 2004
The suppression of excess conductivity with electric field is studied for Bi$_2$Sr$_2$Ca$_{n-1}$Cu$_n$O$_{2n+4+x}$ ($n$ = 1, 2) thin films. A pulse-probe technique is used, which allows for an estimate of the sample temperature.
