Lattice models of random advection and diffusion and their statistics
Stefano Lepri, Paolo Politi, Arkady Pikovsky
We study in detail a one-dimensional lattice model of a continuum, conserved field (mass) that is transferred deterministically between neighbouring random sites. The model falls i…
Domain statistics in the relaxation of the one-dimensional Ising model with strong long-range interactions
Federico Corberi, Manoj Kumar, Eugenio Lippiello +1
After a zero temperature quench, we study the kinetics of the one-dimensional Ising model with long-range interactions between spins at distance decaying as , with $α\l…
Onsager coefficients in a coupled-transport model displaying a condensation transition
Stefano Iubini, Antonio Politi, Paolo Politi
We study nonequilibrium steady states of a one-dimensional stochastic model, originally introduced as an approximation of the Discrete Nonlinear Schrödinger equation. This model is…
Relaxation dynamics and finite-size effects in a simple model of condensation
Gabriele Gotti, Stefano Iubini, Paolo Politi
We consider a simple, purely stochastic model characterized by two conserved quantities (mass density and energy density ) which is known to display a condensation transitio…
Condensation induced by coupled transport processes
Gabriele Gotti, Stefano Iubini, Paolo Politi
Several lattice models display a condensation transition in real space when the density of a suitable order parameter exceeds a critical value. We consider one of such models with…
Frozen dynamics of a breather induced by an adiabatic invariant
Antonio Politi, Paolo Politi, Stefano Iubini
The Discrete Nonlinear Schrödinger (DNLS) equation is a Hamiltonian model displaying an extremely slow relaxation process when discrete breathers appear in the system. In [Iubini S…
