Polaron formation: Ehrenfest dynamics vs. exact results
Guangqi Li, Bijan Movaghar, Abraham Nitzan +1
We use a 1-dimensional tight binding model with an impurity site characterized by electron-vibration coupling, to describe electron transfer and localization at zero temperature, a…
Magnetotransport in the insulating regime of Mn doped GaAs
Louis-Francois Arsenault, B. Movaghar, P. Desjardins +1
We consider transport in the insulating regime of GaMnAs. We calculate the resistance, magnetoresitance and Hall effect, assuming that the Fermi energy is in the region of localize…
Transport in the metallic regime of Mn doped III-V Semiconductors
Louis-Francois Arsenault, B. Movaghar, P. Desjardins +1
The standard model of Mn doping in GaAs is subjected to a coherent potential approximation (CPA) treatment. Transport coefficients are evaluated within the linear response Kubo for…
Hall conductivity in the presence of spin-orbit interaction and disorder
Louis-François Arsenault, B. Movaghar
Starting from the Kubo formula, we expand the Hall conductivity using a cumulant approach which converges quickly at high temperatures (k_BT > energy differences of initial and fin…
Temperature dependence of the charge carrier mobility in gated quasi-one-dimensional systems
Lazaros K. Gallos, Bijan Movaghar, Laurens D. A. Siebbeles
The many-body Monte Carlo method is used to evaluate the frequency dependent conductivity and the average mobility of a system of hopping charges, electronic or ionic on a one-dime…
