Relaxation of the Electron Distribution Function

IEEE Transactions on Plasma Science, 1984
This paper discusses an analytical technique for calculating the relaxation in time of the electron distribution function f in an environment in which no perturbing forces act on the electrons. For t = 0, f may have any arbitrary form presumed to be caused by perturbing forces which were not zero during t < 0.

Relaxation time distribution function

Ferroelectrics, 2000
Abstract The distribution function of relaxation time in disordered dielectrics has been calculated in the random field theory framework. For this purpose, we first consider the dynamics of single two-orientable electric dipole in a random electric field E in a disordered ferroelectric.

Dielectric relaxation functions and models

Journal of Applied Physics, 1990
The dielectric relaxation function is defined as the transient current generated by the application of a unit voltage. In analogy with viscoelasticity, a second relaxation function can be defined as the transient voltage generated by the application of a unit current.

A dispersion function of paramagnetic relaxation

Physica, 1958
Synopsis An empirical dispersion function for paramagnetic relaxation is proposed which is intended to describe experimental data for the magnetic susceptibilities of some alums. This function gives an asymmetric frequency spectrum of the complex susceptibilities, thus an improvement over the function of Casimir and Du Pre in analyzing the ...

On monotonicity of the relaxation functions of viscoelastic materials

Mathematical Proceedings of the Cambridge Philosophical Society, 1970
This note is concerned with one-dimensional viscoelastic materials. Experiments show that for linear materials the relaxation functions are monotone decreasing functions of the time. This monotonic property has not, as far as I am aware, been characterized and in this note I provide a characterization formulated in terms of an assertion about the work ...

New class of creep-relaxation functions

International Journal of Solids and Structures, 1995
It is shown that generalized creep-relaxation functions turn out to be effective in the phenomenologic modelling the complicated materials behaviour, like that in homogenization of heterogeneous bodies and in modelling of the wave propagation and of the negative Poisson ratio phenomena in composites. New directions for fundamental and applied research,
