چکیده

2014 A complete quantum phase shift calculation of several transport coefficients in spin polarized quantum gases (3He, H~ and D~) has been carried out for temperatures ranging from 0.04 K to 10 K and nuclear polarizations M varying from 0 to 1. After a detailed analysis of the dynamical features of the collision, the various direct and exchange « cross sections » necessary to describe the collision between two spin-polarized atoms are studied Emphasis is then placed on some particle-indistinguishability consequences that could be seen in 3He or H~ systems, such as the strong M dependence of the heat capacity, a mode coupling between heat capacity and longitudinal spin diffusion and the oscillatory character of the evolution of the transverse components of M.

Spin-polarized transport through a zigzag-edge graphene flake embedded between two armchair nanoribbons electrodes

We study the coherent spin-polarized transport through a zigzag-edge graphene flake (ZGF), using Hubbard model in the nearest neighbor approximation within the framework of the Green function’s technique and Landauer formalism. The system considered consists of electrode/ (ZGF)/electrode, in which the electrodes are chosen to be armchair nanoribbons. The study was performed for two types of ele...

The Thermodynamic Properties of Polarized Metallic Nanowire in the Presence of Magnetic Field

In this article, the second quantization method has been used to investigate some thermodynamic properties of spin-polarized metallic nanowire in the presence of magnetic field at zero temperature. We have been observed that in different magnetic field, the equilibrium energy of system increases as the density increases. The spin-polarization parameter corresponding to the equilibrium state of ...

A drift-diffusion model for spin-polarized transport in a two-dimensional non-degenerate electron gas controlled by spin–orbit interaction

We apply the Wigner function formalism to derive drift-diffusion transport equations for spin-polarized electrons in a III–V semiconductor single quantum well. The electron spin dynamics is controlled by the spin–orbit interaction which is linear in the momentum. In the transport regime studied, the electron momentum scattering rate is appreciably faster than the spin dynamics. A set of transpo...

Transport properties in a spin polarized gas (I)

The transport properties of a spin polarized gag at low temperature eHeÎ for instance)are studied, the emphasis being put on the particle indistinguishability effects during collisions; the gas is dilute and no degeneracy effects occur. We first study in detail the,partic1e indistinguishability effects in a binary collision and, although all interactions involving the spins are completely ignor...

Thermodynamic properties of polarized liquid 3He along different isentropic paths

The dependence of some thermodynamic properties of spin-polarized liquid 3He such as velocity of sound, adiabatic index, isentropic compressibility and temperature on the spin polarization has been investigated along different isentropic paths. The Lennard-Jones potential has been used in our calculations. It has been found that for higher values of entropy, the spin polarization has greate...
