Explicit characterization of the identity configuration in an Abelian Sandpile Model
Sergio Caracciolo, Guglielmo Paoletti, Andrea Sportiello
Since the work of Creutz, identifying the group identities for the Abelian Sandpile Model (ASM) on a given lattice is a puzzling issue: on rectangular portions of Z^2 complex quasi…
Third virial coefficient for 4-arm and 6-arm star polymers
Sergio Caracciolo, Bortolo Matteo Mognetti, Andrea Pelissetto
We discuss the computation of the third virial coefficient in polymer systems, focusing on an additional contribution absent in the case of monoatomic fluids. We determine the inte…
Hyperforests on the Complete Hypergraph by Grassmann Integral Representation
Andrea Bedini, Sergio Caracciolo, Andrea Sportiello
We study the generating function of rooted and unrooted hyperforests in a general complete hypergraph with n vertices by using a novel Grassmann representation of their generating…
