Spin susceptibilities, spin densities and their connection to spin-currents
Sigurdur I. Erlingsson, John Schliemann, Daniel Loss
We calculate the frequency dependent spin susceptibilities for a two-dimensional electron gas with both Rashba and Dresselhaus spin-orbit interaction. The resonances of the suscept…
Coherent oscillations of current due to nuclear spins
Sigurdur I. Erlingsson, Oleg N. Jouravlev, Yuli V. Nazarov
We propose a mechanism for very slow coherent oscillations of current and nuclear spins in a quantum dot system, that may qualitatively explain some recent experimental observation…
Finite size effects in the magnetization of periodic mesoscopic systems
Sigurdur I. Erlingsson, Andrei Manolescu, Vidar Gudmundsson
We calculate the orbital magnetization of a confined 2DEG as a function of the number of electrons in the system. Size effects are investigated by systematically increasing the are…
The far-infrared absorption of a periodic 2DEG in the transition regime between weak and strong modulation
Vidar Gudmundsson, Ingibjorg Magnusdottir, Sigurdur I. Erlingsson
We study the optical absorption of arrays of quantum dots and antidots in a perpendicular homogeneous magnetic field. The electronic system is described quantum mechanically using…
