Calculating the dynamical dielectric response function for a two-dimensional electron gas (2D EG) under a perpendicular magnetic field and subjected to an additional weak unidirectional periodic magnetic field within the random-phase approximation (RPA), we find that not only is the response functio

Magnetoresistance in a two-dimensional electron gas in a disordered lattice of antidots has been studied for the first time. Commensurability oscillations were found in an array with completely violated short range order. Not quite stochastic trajectories may be responsible for these oscillations in
A combined exciton-cyclotron resonance is found in the photoluminescence excitation and reflectivity spectra of semiconductor quantum wells with an electron gas of low density. In external magnetic fields an incident photon creates an exciton in the ground state and simultaneously excites an electro
