Pure spin current in graphene NS structures
D. Greenbaum, S. Das, G. Schwiete +1
We demonstrate theoretically the possibility to produce a pure spin current in graphene by filtering the charge from a spin-polarized electric current. To achieve this effect, whic…
Temperature dependence of the spin susceptibility of a clean Fermi gas with repulsion
G. Schwiete, K. B. Efetov
Spin susceptibility of a clean Fermi gas with repulsion in any dimension is considered using a supersymmetric low energy theory of interacting spin excitations and renormalization…
Supersymmetry for disordered systems with interaction
G. Schwiete, K. B. Efetov
Considering disordered electron systems we suggest a scheme that allows us to include an electron-electron interaction into a supermatrix sigma-model. The method is based on replac…
Tunneling density of states of granular metals
I. S. Beloborodov, A. V. Lopatin, G. Schwiete +1
We investigate the effect of Coulomb interactions on the tunneling density of states (DOS) of granular metallic systems at the onset of Coulomb blockade regime in two and three dim…
Bosonization for disordered and chaotic systems
K. B. Efetov, G. Schwiete, K. Takahashi
Using a supersymmetry formalism, we reduce exactly the problem of electron motion in an external potential to a new supermatrix model valid at all distances. All approximate nonlin…
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…
