Critical behavior of repulsive dimers on square lattices at 2/3 monolayer coverage
F. Roma, J. L. Riccardo, A. J. Ramirez-Pastor
Monte Carlo simulations and finite-size scaling theory have been used to study the critical behavior of repulsive dimers on square lattices at 2/3 monolayer coverage. A "zig-zag" (…
A c-theorem for the entanglement entropy
H. Casini, M. Huerta
The combination of the Lorentz symmetry and the strong subadditive property of the entropy leads to a c-theorem for the entanglement entropy in 1+1 dimensions. We present a simple…
Observing the evaporation transition in vibro-fluidized granular matter
Jorge E. Fiscina, Manuel O. Caceres
By shaking a sand box the grains on the top start to jump giving the picture of evaporating a sand bulk, and a gaseous transition starts at the surface granular matter (GM) bed. Mo…
Synchronization and structure in an adaptive oscillator network
Pablo M. Gleiser, Damián H. Zanette
We analyze the interplay of synchronization and structure evolution in an evolving network of phase oscillators. An initially random network is adaptively rewired according to the…
Influence of global correlations on central limit theorems and entropic extensivity
John A. Marsh, Miguel A. Fuentes, Luis G. Moyano +1
We consider probabilistic models of N identical distinguishable, binary random variables. If these variables are strictly or asymptotically independent, then, for N>>1, (i) the att…
Coevolution of agents and networks: Opinion spreading and community disconnection
Santiago Gil, Damian H. Zanette
We study a stochastic model for the coevolution of a process of opinion formation in a population of agents and the network which underlies their interaction. Interaction links can…
