Dynamics of short time--scale energy relaxation of optical excitations due to electron--electron scattering in the presence of arbitrary disorder
Imre Varga, Peter Thomas, Torsten Meier +1
A non--equilibrium occupation distribution relaxes towards the Fermi--Dirac distribution due to electron--electron scattering even in finite Fermi systems. The dynamic evolution of…
On Renyi entropies characterizing the shape and the extension of the phase space representation of quantum wave functions in disordered systems
I. Varga, J. Pipek
We discuss some properties of the generalized entropies, called Renyi entropies and their application to the case of continuous distributions. In particular it is shown that these…
Dynamics of Coulomb-correlated electron-hole pairs in disordered semiconductor nanowires
I. Varga, C. Schlichenmaier, T. Meier +3
The dynamics of optically generated electron-hole pairs is investigated in a disordered semiconductor nanowire. The particle pairs are generated by short laser pulses and their dyn…
Quantum Localization near Bifurcations in Classically Chaotic Systems
I. Varga, P. Pollner, B. Eckhardt
We show that strongly localized wave functions occur around classical bifurcations. Near a saddle node bifurcation the scaling of the inverse participation ratio on Planck's consta…
