Abstract

The quantum plasma of Bose and Fermi particles is considered. A scheme of equation linearization for density matrix with the exchange interaction taken in account is proposed and the equation solution is found. An expression for Hartreeโ€ Fock dielectric permeatability with the exchange interaction is obtained. This interaction is taken into account in the exchange scattering amplitude. With the use of obtained solutions the nonโ€equilibrium spectral function of electric field fluctuations in presence of exchange interaction and medium polarization is found. It is shown that in the state of thermodynamic equilibrium a Fluctuationโ€Dissipation Theorem holds. An expression for the system's response to an external electric field in presence of exchange interaction is given (ยฉ 2009 WILEYโ€VCH Verlag GmbH & Co. KGaA, Weinheim)

In this paper we investigate the electric interaction between a charged particle and a surface in which the charged ions are capable of moving in response to the electric potential disturbance caused by the approach of the charged particle. Such surfaces include ionic surfactants distributed in air-

The electromagnetic field of a charged particle with hyperbolic motion is described. The field of a particle with eternal hyperbolic motion is found by taking the limit of a situation with limited hyperbolic motion. The flow of energy in the electromagnetic field is discussed.

An experimental test constraining the intrinsic time scale of a primary physical mechanism that detects extremely-low-frequency (ELF) magnetic fields in biological systems is proposed. The suggested test postulates that a transductive mechanism operating on time scales much shorter than the period o
