Ground state optimization and hysteretic demagnetization: the random-field Ising model
Mikko J. Alava, Vittorio Basso, Francesca Colaiori +4
We compare the ground state of the random-field Ising model with Gaussian distributed random fields, with its non-equilibrium hysteretic counterpart, the demagnetized state. This i…
Phase transitions in a disordered system in and out of equilibrium
F. Colaiori, M. J. Alava, G. Durin +2
The equilibrium and non--equilibrium disorder induced phase transitions are compared in the random-field Ising model (RFIM). We identify in the demagnetized state (DS) the correct…
Detecting communities in large networks
Andrea Capocci, Vito D. P. Servedio, Guido Caldarelli +1
We develop an algorithm to detect community structure in complex networks. The algorithm is based on spectral methods and takes into account weights and links orientations. Since t…
Average trajectory of returning walks
Francesca Colaiori, Andrea Baldassarri, Claudio Castellano
We compute the average shape of trajectories of some one--dimensional stochastic processes x(t) in the (t,x) plane during an excursion, i.e. between two successive returns to a ref…
