Linear mode analysis from spin transport equation

Saturation and Linear Transport Equation

We show that the GBW saturation model provides an exact solution to the one dimensional linear transport equation. We also show that it is motivated by the BK equation considered in the saturated regime when the diffusion and the splitting term in the diffusive approximation are balanced by the nonlinear term.

Diffusion equation and spin drag in spin-polarized transport

TRANSPORT EQUATION WITH FUZZY DATA

In this paper, we use the generalized differentiability concept tostudy the fuzzy transport equation. We consider transport equationin the homogeneous and non-homogeneous cases with fuzzy initialcondition. We also present the solution when speed parameter is a fuzzynumber. Our method is based on the construction of the solutionsby employing Zadeh's extension principle.

Diffusion models for spin transport derived from the spinor Boltzmann equation

The aim of this paper is to derive and analyse diffusion models for semiconductor spintronics. We begin by presenting and studying the so called ”spinor” Boltzmann equation. Starting then from a rescaled version of linear Boltzmann equation with different spin-flip and non spin-flip collision operators, different continuum (drift-diffusion) models are derived. By comparing the strength of the s...

Spin and Isospin Asymmetry, Equation of State and Neutron Stars

In the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. We have also investigated the structure of neutron stars. According to our results, the spin asymmetry stiens the equation of state and leads to high mass for the neutron star.
