From Equilibrium Criticality to Universal Collective Phases through Nonreciprocal Coupling of Ordered Systems
Fabrizio Rippa, Jacopo A. Garofalo, Eugenio Lippiello
Nonreciprocal interactions have emerged as a fundamental driver of collective behavior far from equilibrium. Here, we show that nonreciprocal couplings between spin systems whose i…
Domain Growth in Long-range Ising Models with Disorder

Recent advances have highlighted the rich low-temperature kinetics of the long-range Ising model (LRIM). This study investigates domain growth in an LRIM with quenched disorder, fo…

Ramgopal Agrawal, Federico Corberi, Eugenio Lippiello +1
We investigate the influence of long-range (LR) interactions on the phase ordering dynamics of the one-dimensional random field Ising model (RFIM). Unlike the usual RFIM, a spin in…

Quasi-deterministic dynamics, memory effects, and lack of self-averaging in the relaxation of quenched ferromagnets
Federico Corberi, Eugenio Lippiello, Paolo Politi
We discuss the interplay between the degree of dynamical stochasticity, memory persistence and violation of the self-averaging property in the aging kinetics of quenched ferromagne…

Federico Corberi, Eugenio Lippiello, Paolo Politi
The equilibrium and nonequilibrium properties of ferromagnetic systems may be affected by the long-range nature of the coupling interaction. Here we study the phase separation proc…
One dimensional phase-ordering in the Ising model with space decaying interactions
Federico Corberi, Eugenio Lippiello, Paolo Politi
The study of the phase ordering kinetics of the ferromagnetic one-dimensional Ising model dates back to 1963 for non conserved order parameter (NCOP) and to 1991 for conserved orde…

We study numerically the aging properties of the two-dimensional Ising model with quenched disorder considered in our recent paper [Phys. Rev. E 95, 062136 (2017)], where frustrati…
Synchronized oscillations and acoustic fluidization in confined granular materials
F. Giacco, L. de Arcangelis, M. Pica Ciamarra +1
According to the acoustic fluidization hypothesis, elastic waves at a characteristic frequency form inside seismic faults even in the absence of an external perturbation. These wav…

We study numerically a two-dimensional random-bond Ising model where frustration can be tuned by varying the fraction of antiferromagnetic coupling constants. At low temperatur…
On a relation between roughening and coarsening
Federico Corberi, Eugenio Lippiello, Marco Zannetti
We argue that a strict relation exists between two in principle unrelated quantities: The size of the growing domains in a coarsening system, and the kinetic roughening of an inter…
