"... 1 While microscopic laws of physics are invariant under the reversal of the arrow of time, the transport of energy and information in most devices is an irreversible process. It is this irreversibility that leads to intrinsic dissipations in electronic devices and limits the possibility of quantum c ..."

computation. We theoretically predict that the electric field can induce a substantial amount of dissipationless quantum spin current at room temperature, in hole doped semiconductors such as Si, Ge and GaAs. Based on a generalization of the quantum Hall effect, the predicted effect leads to efficient spin

Quantum theory of the Hall effect
 Int. J. Theor. Phys
, 1997
"... We discuss a model of both classical and integer quantum Halleffect which is based on a semiclassical SchroedingerChernSimonsaction, where the Ohmequations result as equations of motion. The quantization of the classical ChernSimonspart of action under typical quantum Hall conditions results ..."

The Fractional Quantum Hall Effect
, 1999
"... Abstract We give a brief introduction to the phenomenon of the Fractional Quantum Hall effect, whose discovery was awarded the Nobel prize in 1998. We also explain the composite fermion picture which describes the fractional quantum Hall effect as the integer quantum Hall effect of composite fermion ..."

Line and the Quantum Hall Effect
, 2001
"... Abstract: We present a finite dimensional matrix model associated to the noncommutative ChernSimons theory, obtained by inserting a Wilson line. For a specific choice of the representation of the Wilson line the model is equivalent to minimal modification of the matrix model which is compatible wit ..."

The Quantum Hall Effect
"... localized states. A plateau will appear when the Fermi level happens lying in localized regions. Prominently, the magnitude of Hall conductance (reciprocal of Hall resistance), in the unit of RK2 15e2/h, turns out exactly to be the number of occupied bands. This is not trivial. The quantization of H ..."

insulators and superconductors[3], IQHE belongs to class A (unitary class), whose space of quantum ground states in 2D is partitioned into topological sectors labeled by an integer (here the filling factor). One feature of quantum Hall states is their featureless: different quantum Hall liquids have the same

"... Abstract. Based on Mndoped chalcopyrite ZnSiAs 2 the new dilute magnetic semiconductor with ptype conductivity was produced. The Curie temperature behaviour of the produced semiconductor is distinctly dependent on the Mn concentration: 325 K for 1 wt.% and 337 K for 2 wt.% of Mn, consequently. Ma ..."
