چکیده
abstract Recently it has been suggested by A. M. Tsvelik that quantum S=1/2 an-tiferromagnet can be described by the Majorana fermions in an irreducible way and without any constraint. In contrast to this claim we shall show that this representation is highly reducible. It is a direct sum of four irreducible fundamental representations of su(2) algebra.

We develop a quasiclassical method based on the path integral formalism, to study the influence of disorder on magnetooscillations of the density of states and conductivity. The treatment is appropriate for electron systems in the presence of a random potential with large correlation length or a random magnetic field, which are characterisitic features of various 2D electronic systems presently...

A rigorous hydrodynamic theory of the A-B transition is presented. All dissi-pative processes are considered. At low interface velocities, those occurring on hy-drodynamic length scales, not considered hitherto, are most probably the dominant ones.

We implement Wilson fermions on 2D Lorentzian triangulation and determine the spectrum of the Dirac-Wilson operator. We compare it to the spectrum of the corresponding operator in the Euclidean background. We use fermionic particle to probe the fractal properties of Lorentzian gravity coupled to c = 1/2 and c = 4 matter. We numerically determine the scaling exponent of the mass gap M ∼ N −1/dH ...

Based on a large number of smearing steps, we classify SU(3) gauge field configurations in different topological sectors. For each sector we compare the exact analytical predictions for the microscopic Dirac operator spectrum of quenched staggered fermions. In all sectors we find perfect agreement with the predictions for the sector of topological charge zero, showing explicitly that the smalle...

We consider the " fractional quantum Hall atom " in the vanishing Zeeman energy limit, and investigate the validity of Hund's maximum-spin rule for interacting electrons in various Landau levels. While it is not valid for electrons in the lowest Landau level, there are regions of filling factors where it predicts the ground state spin correctly provided it is applied to composite fermions. The ...
