Algebraic coarsening in voter models with intermediate states
Luca Dall'Asta, Tobias Galla
The introduction of intermediate states in the dynamics of the voter model modifies the ordering process and restores an effective surface tension. The logarithmic coarsening of th…
Entropy landscape and non-Gibbs solutions in constraint satisfaction problems
L. Dall'Asta, A. Ramezanpour, R. Zecchina
We study the entropy landscape of solutions for the bicoloring problem in random graphs, a representative difficult constraint satisfaction problem. Our goal is to classify which t…
Effective surface-tension in the noise-reduced voter model
Luca Dall'Asta, Claudio Castellano
The role of memory is crucial in determining the properties of many dynamical processes in statistical physics. We show that the simple addition of memory, in the form of noise red…
Non-equilibrium phase transition in negotiation dynamics
A. Baronchelli, L. Dall'Asta, A. Barrat +1
We introduce a model of negotiation dynamics whose aim is that of mimicking the mechanisms leading to opinion and convention formation in a population of individuals. The negotiati…
Agreement dynamics on small-world networks
Luca Dall'Asta, Andrea Baronchelli, Alain Barrat +1
In this paper we analyze the effect of a non-trivial topology on the dynamics of the so-called Naming Game, a recently introduced model which addresses the issue of how shared conv…
Exact solution of the one-dimensional deterministic Fixed-Energy Sandpile
Luca Dall'Asta
In reason of the strongly non-ergodic dynamical behavior, universality properties of deterministic Fixed-Energy Sandpiles are still an open and debated issue. We investigate the on…
