Relaxation of hot electrons in a degenerate two-dimensional electron system: transition to one-dimensional scattering
D. Taubert, C. Tomaras, G. J. Schinner +4
The energy relaxation channels of hot electrons far from thermal equilibrium in a degenerate two-dimensional electron system are investigated in transport experiments in a mesoscop…
Scaling approach for the time-dependent Kondo model
C. Tomaras, S. Kehrein
We present a new nonperturbative method to deal with the time-dependent quantum many-body problem, which is an extension of Wegner's flow equations to time-dependent Hamiltonians.…
An electron jet pump: The Venturi effect of a Fermi liquid
D. Taubert, G. J. Schinner, C. Tomaras +3
A three-terminal device based on a two-dimensional electron system is investigated in the regime of non-equilibrium transport. Excited electrons scatter with the cold Fermi sea and…
Electron-avalanche amplifier based on the electronic Venturi effect
D. Taubert, G. J. Schinner, H. P. Tranitz +4
Scattering of otherwise ballistic electrons far from equilibrium is investigated in a cold two-dimensional electron system. The interaction between excited electrons and the degene…
Vibrational excitations in systems with correlated disorder
W. Schirmacher, B. Schmid, C. Tomaras +4
We investigate a -dimensional model ( = 2,3) for sound waves in a disordered environment, in which the local fluctuations of the elastic modulus are spatially correlated with…
