Limited resolution in complex network community detection with Potts model approach
Jussi M. Kumpula, Jari Saramaki, Kimmo Kaski +1
According to Fortunato and Barthelemy, modularity-based community detection algorithms have a resolution threshold such that small communities in a large network are invisible. Her…
Microscopic modeling of photoluminescence of strongly disordered semiconductors
P. Bozsoki, M. Kira, W. Hoyer +4
A microscopic theory for the luminescence of ordered semiconductors is modified to describe photoluminescence of strongly disordered semiconductors. The approach includes both diag…
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…
Avalanche Dynamics in Wet Granular Media
P. Tegzes, T. Vicsek, P. Schiffer
A detailed characterization of avalanche dynamics of wet granular media in a rotating drum apparatus is presented. The results confirm the existence of the three wetness regimes ob…
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…
