Slow relaxation of magnetoresistance in doped p -GaAs/AlGaAs layers with partially filled upper Hubbard band
N. V. Agrinskaya, V. I. Kozub, D. V. Shamshur +1
We observed slow relaxation of magnetoresistance in quantum well structures GaAs-AlGaAs with a selective doping of both wells and barrier regions which allowed partial filling of t…

The resonant circular photogalvanic effect is observed in wurtzite (0001)-oriented GaN low-dimensional structures excited by infrared radiation. The current is induced by angular m…
Fine structure and optical pumping of spins in individual semiconductor quantum dots
Allan S. Bracker, Daniel Gammon, Vladimir L. Korenev
We review spin properties of semiconductor quantum dots and their effect on optical spectra. Photoluminescence and other types of spectroscopy are used to probe neutral and charged…
Nonequilibrium kinetics of a disordered Luttinger liquid
D. A. Bagrets, I. V. Gornyi, D. G. Polyakov
We develop a kinetic theory for strongly correlated disordered one-dimensional electron systems out of equilibrium, within the Luttinger liquid model. In the absence of inhomogenei…

K. V. Kavokin
Experiments on the effect of radio-frequency (RF) magnetic fields on the magnetic compass orientation of migratory birds are analyzed using the theory of magnetic resonance. The re…

A. G. Yashenkin, I. V. Gornyi, A. D. Mirlin +1
We study the influence of spin on the quantum interference of interacting electrons in a single-channel disordered quantum wire within the framework of the Luttinger liquid (LL) mo…
