How the site degree influences quantum probability on inhomogeneous substrates
A. M. C. Souza, R. F. S. Andrade, N. A. M. Araújo +1
We investigate the effect of the node degree and energy on the electronic wave function for regular and irregular structures, namely, regular lattices, disordered percolation c…
Quantum Criticality in a Bosonic Josephson Junction
P. Buonsante, R. Burioni, E. Vescovi +1
In this paper we consider a bosonic Josephson junction described by a two-mode Bose-Hubbard model, and we thoroughly analyze a quantum phase transition occurring in the system in t…
Microscopic energy flows in disordered Ising spin systems
Elena Agliari, Mario Casartelli, Alessandro Vezzani
An efficient microcanonical dynamics has been recently introduced for Ising spin models embedded in a generic connected graph even in the presence of disorder i.e. with the spin co…
Quantum signatures of self-trapping transition in attractive lattice bosons
P. Buonsante, V. Penna, A. Vezzani
We consider the Bose-Hubbard model describing attractive bosonic particles hopping across the sites of a translation-invariant lattice, and compare the relevant ground-state proper…
Energy Transport in an Ising Disordered Model
Elena Agliari, Mario Casartelli, Alessandro Vezzani
We introduce a new microcanonical dynamics for a large class of Ising systems isolated or maintained out of equilibrium by contact with thermostats at different temperatures. Such…
Phase ordering and universality for continuous symmetry models on graphs
R. Burioni, F. Corberi, A. Vezzani
We study the phase-ordering kinetics following a temperature quench of O(N) continuous symmetry models with and 4 on graphs. By means of extensive simulations, we show that the glo…
