Weak Localization and Integer Quantum Hall Effect in a Periodic Potential
G. Schwiete, D. Taras-Semchuk, K. B. Efetov
We consider magnetotransport in a disordered two-dimensional electron gas in the presence of a periodic modulation in one direction. Existing quasiclassical and quantum approaches…
Quantum interference and the formation of the proximity effect in chaotic normal-metal/superconducting structures
D. Taras-Semchuk, Alexander Altland
We discuss a number of basic physical mechanisms relevant to the formation of the proximity effect in superconductor/normal metal (SN) systems. Specifically, we review why the prox…
Effect of Long Range Disorder on Electron Motion in Two Dimensions
D. Taras-Semchuk, K. B. Efetov
We consider a two-dimensional electron gas with long range disorder. Assuming that time reversal symmetry is broken either by an external magnetic field or, as in the case of a del…
Antilocalization in a 2D Electron Gas in a Random Magnetic Field
D. Taras-Semchuk, K. B. Efetov
We construct a supersymmetric field theory for the problem of a two-dimensional electron gas in a random, static magnetic field. We find a new term in the free energy, additional t…
Superfluid Flow Past an Array of Scatterers
D. Taras-Semchuk, J. M. F. Gunn
We consider a model of nonlinear superfluid flow past a periodic array of point-like scatterers in one dimension. An application of this model is the determination of the critical…
