Role of interchain hopping on electron spin relaxation in quasi-one-dimensional case

Role of interchain hopping on electron spin relaxation in quasi-one-dimensional case

2014 Theories cannot actually predict the value and the T-dependence of the electronic spin resonance linewidth of organic conductors. To compensate this difficulty, most of the experiments have been carried out on families of compounds. In order to reduce the number of parameters, we have modified on the same compound (TTF-TCNQ) the interchain coupling by introducing chain breakings. We observ...

Calculation of Quasi-one-dimensional Interacting Electron Gas Using the Hartree-Fock Method

In this paper, the Hartree-Fock method has been formulated to investigate some of the ground state properties of quasi-one-dimensional interacting electron gas in the presence of the magnetic field. The bare coulomb interaction between electrons has been assumed. For this system, we have also computed some of its thermodynamic and magnetic properties such as the energy, pressure, incompressibil...

Quasi - one - dimensional spin - density - wave states in the presence of two commensurate potentials and an interchain misfit

Spin density wave (SDW) states of a quasi-one-dimensional system with an incommensu-rate wave vector perpendicular to the chain have been studied in the presence of two kinds of commensurate potentials, which originate in a quarter-filled band and dimerization along the chain. In terms of a phase variable of the SDW order parameter, we treat classically the two-dimensional Hamiltonian, which in...

Spin resolved energy parametrization of a quasi-one-dimensional electron gas

By carrying out extensive lattice regularized diffusion Monte Carlo calculations, we study the spin and density dependence of the ground state energy for a quasi-one-dimensional electron gas, with harmonic transverse confinement and long-range 1/r interactions. We present a parametrization of the exchangecorrelation energy suitable for spin density functional calculations, which fulfills exact ...
