Network node immunization: improving Netshield algorithm through random rooted forests
Luca Avena, Alexandre Gaudillière, Irina Gurewitsch +2
We are interested in the so-called multiple-node immunization problem for complex networks under attack by a viral agent. It consists in identifying and removing a set of nodes of…
On some features of Quadratic Unconstrained Binary Optimization with random coefficients
Marco Isopi, Benedetto Scoppola, Alessio Troiani
Quadratic Unconstrained Binary Optimization (QUBO or UBQP) is concerned with maximizing/minimizing the quadratic form with a matrix…
Shaken Dynamics on the 3-D Cubic Lattice
Benedetto Scoppola, Alessio Troiani, Matteo Veglianti
On the space of spin configurations on the 3-square lattice, we consider the \emph{shaken dynamics}, a parallel Markovian dynamics that can be interpreted in terms of Pr…
Metastability for the Ising model on the hexagonal lattice
Valentina Apollonio, Vanessa Jacquier, Francesca Romana Nardi +1
We consider the Ising model on the hexagonal lattice evolving according to Metropolis dynamics. We study its metastable behavior in the limit of vanishing temperature when the syst…
Tides and dumbbell dynamics
Benedetto Scoppola, Alessio Troiani, Matteo Veglianti
We discuss a model describing the effects of tidal dissipation on satellite's orbits. Tidal bulges are described in terms of a dumbbell, coupled to the rotation by a dissipative in…
Lonely planets and light belts: the Statistical Mechanics of Gravitational Systems
Gabriella Pinzari, Benedetto Scoppola, Alessio Troiani
In this paper we propose a notion of stability, that we call -stability, for systems of particles interacting via Newton's gravitational potential, and orbiting a much bigger…
