Phase-locking dynamics of heterogeneous oscillator arrays
Stefano Lepri, Arkady Pikovsky
We consider an array of nearest-neighbor coupled nonlinear autonomous oscillators with quenched random frequencies and purely conservative coupling. We show that global phase-locke…
Classical and quantum harmonic mean-field models coupled intensively and extensively with external baths
Francesco Andreucci, Stefano Lepri, Stefano Ruffo +1
We study the nonequilibrium steady-state of a fully-coupled network of quantum harmonic oscillators, interacting with two thermal reservoirs. Given the long-range nature of the…
Hydrodynamics and transport in the long-range-interacting chain
Stefano Iubini, Stefano Lepri, Stefano Ruffo
We present a simulation study of the one-dimensional lattice theory with long-range interactions decaying as an inverse power of the intersite distance , $σ>0…
Mechanisms for transient localization in a diatomic nonlinear chain
Stefano Lepri, Francesco Piazza
We investigate transient nonlinear localization, namely the self-excitation of energy bursts in an atomic lattice at finite temperature. As a basic model we consider the diatomic L…
Heat conduction in a three-dimensional momentum-conserving fluid
Rongxiang Luo, Lisheng Huang, Stefano Lepri
Size-dependence of energy transport and the effects of reduced dimensionality on transport coefficients are of key importance for understanding nonequilibrium properties of matter…
Kinetic and hydrodynamic regimes in multi-particle-collision dynamics of a one-dimensional fluid with thermal walls
Stefano Lepri, Guido Ciraolo, Pierfrancesco Di Cintio +2
We study the non-equilibrium steady-states of a one-dimensional () fluid in a finite space region of length . Particles interact among themselves by multi-particle collisi…
