Statistical Physics of Group Testing
Marc Mezard, Marco Tarzia, Cristina Toninelli
This paper provides a short introduction to the group testing problem, and reviews various aspects of its statistical physics formulation. Two main issues are discussed: the optima…
Statistical Mechanics of the Hyper Vertex Cover Problem
M. Mézard, M. Tarzia
We introduce and study a new optimization problem called Hyper Vertex Cover. This problem is a generalization of the standard vertex cover to hypergraphs: one seeks a configuration…
On the absence of the glass transition in two dimensional hard disks
M. Tarzia
In this paper we study the glass transition in a model of identical hard spheres, focusing on the two dimensional case. In the mean-field limit the model exhibits an ideal glass tr…
Size segregation in granular media induced by phase transition
M. Tarzia, A. Fierro, M. Nicodemi +2
In order to study analytically the nature of the size segregation in granular mixtures, we introduce a mean field theory in the framework of a statistical mechanics approach, based…
Jamming transition in granular media: A mean field approximation and numerical simulations
A. Fierro, M. Nicodemi, M. Tarzia +2
In order to study analytically the nature of the jamming transition in granular material, we have considered a cavity method mean field theory, in the framework of a statistical me…
Segregation in fluidized versus tapped packs
Marco Tarzia, Annalisa Fierro, Mario Nicodemi +1
We compare the predictions of two different statistical mechanics approaches, corresponding to different physical measurements, proposed to describe binary granular mixtures subjec…
