Ising model with memory: coarsening and persistence properties
Fabio Caccioli, Silvio Franz, Matteo Marsili
We consider the coarsening properties of a kinetic Ising model with a memory field. The probability of a spin-flip depends on the persistence time of the spin in a state. The more…
Number of cliques in random scale-free network ensembles
Ginestra Bianconi, Matteo Marsili
In this paper we calculate the average number of cliques in random scale-free networks. We consider first the hidden variable ensemble and subsequently the Molloy Reed ensemble. In…
Statistical mechanics of combinatorial auctions
Tobias Galla, Michele Leone, Matteo Marsili +3
Combinatorial auctions are formulated as frustrated lattice gases on sparse random graphs, allowing the determination of the optimal revenue by methods of statistical physics. Tran…
Scale-free networks with an exponent less than two
Hamed Seyed-allaei, Ginestra Bianconi, Matteo Marsili
We study scale free simple graphs with an exponent of the degree distribution less than two. Generically one expects such extremely skewed networks -- which occur very frequent…
A statistical mechanics model for the emergence of consensus
Giacomo Raffaelli, Matteo Marsili
The statistical properties of pairwise majority voting over S alternatives is analyzed in an infinite random population. We first compute the probability that the majority is trans…
Stylized facts in minority games with memory: a new challenge
Damien Challet, Matteo Marsili, Andrea De Martino
A finite memory is introduced in the score dynamics of Minority Games. As expected, this removes the dependence of the stationary state on the initial conditions. However, it also…
