The quantum interference corrections to the conductivity are calculated for an electron gas in asymmetric quantum wells in a magnetic field. The theory takes into account two different types of the spin splitting of the conduction band: the Dresselha

The problem of strongly correlated disordered two-dimensional electron gas on a lattice is studied by computer modeling. The long-range Coulomb interaction is assumed. It is proved that for zero hopping amplitude J the lowest residue of the one-parti

A new quantum Monte-Carlo method, efficient for system with diagonal-dominated Hamiltonians, is proposed. The eigenstates are found by diagonalization of the Hamiltonian in a truncated basis generated by a Monte-Carlo algorithm. The method is applied

A model of a classical electron liquid without external disorder is applied to two-dimensional electrons in a strong magnetic field. Computer modeling gives a quantitative explanation for the recently observed gap in the tunneling current of a double

We show that by investigating the exciton magnetoluminescence of type II GaAs/AlAs superlattices one can establish the nature of the additional exchange splitting, observed experimentally in such superlattices. This splitting is attributed to the sym

The theory for the exciton magnetoluminescence in GaAs/AlAs superlattices is presented. We find the energies of the exciton states, taking into account an additional exchange splitting, caused by the symmetry reduction from D 2d to C 2v . We show tha

We have studied, theoretically, the exciton luminescence of type II GaAs/AlAs superlattices in a magnetic field. If such superlattices are grown along z ‖[001], the states, allowed in luminescence polarized along x '‖[110] or y '‖[1-0], are spl

The thermodynamic density of states is calculated taking into account both linear and non-linear electron screening. In the linear screening regime the density of states is negative, and it is determined by electron-electron interaction. The linear s

We solve numerically the equation for the charge distribution in a 2 D strip in the quantum Hall effect regime, derived earlier [1], and obtain the current-voltage dependence. We find that in the Corbino geometry the current grows exponentially with

We have developed a theory of the negative magnetoresistance due to the weak localization in uniaxial wurtzite-type crystals, in which the spin splitting of the conduction band is linear in the wave vector, unlike the cubic ${\rm A_3 B_5}$ crystals.
