Integer quantum Hall conductivity and longitudinal conductivity in silicene under the electric field and magnetic field

Study of leaky dielectric droplet behavior under an electric field: effect of viscosity and electric conductivity ratios

In this research, hydrodynamic behavior of a leaky dielectric droplet under an electric field is simulated. The level set method is used for interface tracking and the ghost fluid method is used for modeling discontinuous quantities at interface. Using Taylor’s leaky dielectric model, electric field and electric force at the interface is calculated. Simulation results show the droplet deformati...

Frequency dependent conductivity in the integer quantum Hall effect

Abstract. Frequency dependent electronic transport is investigated for a two-dimensional disordered system in the presence of a strong perpendicular static magnetic field. The acconductivity is calculated numerically from Kubo’s linear response theory using a recursive Green’s function technique. In the tail of the lowest Landau band, we find a linear frequency dependence for the imaginary part...

Electric Field Induced Hopping Conductivity and Polarization in Hytrel

Activated conductivity in the quantum Hall effect.

Activated dissipative conductivity ¢==o-*~exp(-A/T) and the activated deviation of the Hall conductivity from the precise quanfizafion &r~v=~i e2 /h f~exp ( -A /T ) are studied in a plateau range of the quantum Hall effect. The prefactors cr*~ and o*~ are calculated for the case of a long-range random potential in the fxa~ework of a classical theory. There is a range of temperatures Tx << T<< T...

Imaging electric conductivity and conductivity anisotropy via eddy currents induced by pulsed field gradients

PURPOSE: The capacity to measure conductivity and conductivity anisotropy in vivo and non-invasively has practical significance in a number of biomedical applications. For example, large changes of tissue conductivity have been reported in tumors, strokes and myocardial infarction. Considerable early efforts were focused on the measurement of injected low-frequency currents (1-3). Electric prop...
