Condensation transition and ensemble inequivalence in the Discrete Nonlinear Schrödinger Equation
Giacomo Gradenigo, Stefano Iubini, Roberto Livi +1
The thermodynamics of the discrete nonlinear Schrödinger equation in the vicinity of infinite temperature is explicitly solved in the microcanonical ensemble by means of large-devi…
Statistical Mechanics of Systems with Negative Temperature
Marco Baldovin, Stefano Iubini, Roberto Livi +1
Do negative absolute temperatures matter physics and specifically Statistical Physics? We provide evidence that we can certainly answer positively to this vexata quaestio. The grea…
Chaos and localization in the Discrete Nonlinear Schrödinger Equation
Stefano Iubini, Antonio Politi
We analyze the chaotic dynamics of a one-dimensional discrete nonlinear Schrödinger equation. This nonintegrable model, ubiquitous in several fields of physics, describes the behav…
Negative-temperature Fourier transport in one-dimensional systems
Marco Baldovin, Stefano Iubini
We investigate nonequilibrium steady states in a class of one-dimensional diffusive systems that can attain negative absolute temperatures. The cases of a paramagnetic spin system,…
Dephasing-assisted macrospin transport
S. Iubini, S. Borlenghi, A. Delin +2
Transport phenomena are ubiquitous in physics, and it is generally understood that the environmental disorder and noise deteriorates the transfer of excitations. There are however…
Aging of living polymer networks: a model with patchy particles
Stefano Iubini, Marco Baiesi, Enzo Orlandini
Microrheology experiments show that viscoelastic media composed by wormlike micellar networks display complex relaxations lasting seconds even at the scale of micrometers. By mappi…
