Current Fluctuations and Statistics During a Large Deviation Event in an Exactly-Solvable Transport Model
Pablo I. Hurtado, Pedro L. Garrido
We study the distribution of the time-integrated current in an exactly-solvable toy model of heat conduction, both analytically and numerically. The simplicity of the model allows…
Demagnetization via Nucleation of the Nonequilibrium Metastable Phase in a Model of Disorder
Pablo I. Hurtado, J. Marro, P. L. Garrido
We study both analytically and numerically metastability and nucleation in a two-dimensional nonequilibrium Ising ferromagnet. Canonical equilibrium is dynamically impeded by a wea…
Metastability, nucleation, and noise-enhanced stabilization out of equilibrium
Pablo I. Hurtado, J. Marro, P. L. Garrido
We study metastability and nucleation in a kinetic two-dimensional Ising model which is driven out of equilibrium by a small random perturbation of the usual dynamics at temperatur…
Breakdown of Hydrodynamics in a Simple One-Dimensional Fluid
Pablo I. Hurtado
We investigate the behavior of a one-dimensional diatomic fluid under a shock wave excitation. We find that the properties of the resulting shock wave are in striking contrast with…
The Simplest Piston Problem II: Inelastic Collisions
P. I. Hurtado, S. Redner
We study the dynamics of three particles in a finite interval, in which two light particles are separated by a heavy ``piston'', with elastic collisions between particles but inela…
The Simplest Piston Problem I: Elastic Collisions
P. I. Hurtado, S. Redner
We study the dynamics of three elastic particles in a finite interval where two light particles are separated by a heavy ``piston''. The piston undergoes surprisingly complex motio…
