Quantum Magnets with Anisotropic Infinite Range Random Interactions
Liliana Arrachea, Marcelo J. Rozenberg
Using exact diagonalization techniques we study the dynamical response of the anisotropic disordered Heisenberg model for systems of S=1/2 spins with infinite range random exchange…

Dynamical patterns of epidemic outbreaks in complex heterogeneous networks
Marc Barthelemy, Alain Barrat, Romualdo Pastor-Satorras +1
We present a thorough inspection of the dynamical behavior of epidemic phenomena in populations with complex and heterogeneous connectivity patterns. We show that the growth of the…

Long range disorder and Anderson transition in systems with chiral symmetry
Antonio M. Garcia-Garcia, Kazutaka Takahashi
We study the spectral properties of a chiral random banded matrix (chRBM) with elements decaying as a power-law . This model is equivalent to a chir…
