Negative fluctuation-dissipation ratios in the backgammon model
A. Garriga, I. Pagonabarraga, F. Ritort
We analyze fluctuation-dissipation relations in the Backgammon model: a system that displays glassy behavior at zero temperature due to the existence of entropy barriers. We study…
Mode-Dependent nonequilibrium temperature in aging systems
A. Garriga, F. Ritort
We introduce an exactly solvable model for glassy dynamics with many relaxational modes, each one characterized by a different relaxational time-scale. Analytical solution of the a…
Universality of Fluctuation-Dissipation Ratios: The Ferromagnetic Model
A. Garriga, P. Sollich, I. Pagonabarraga +1
We calculate analytically the fluctuation-dissipation ratio (FDR) for Ising ferromagnets quenched to criticality, both for the long-range model and its short-range analogue in the…
Zero-th law in structural glasses: an example
Adan Garriga
We investigate the validity of a zeroth thermodynamic law for non-equilibrium systems. In order to describe the thermodynamics of the glassy systems, it has been introduced an extr…
Strong Soret effect in one dimension
Adan Garriga, Jorge Kurchan, Felix Ritort
We consider a one-dimensional gas of two kinds of particles with different masses interacting through short range interactions. The system exhibits an extreme form of the Soret eff…
Heat transfer and Fourier's law in off-equilibrium systems
Adan Garriga, Felix Ritort
We study the most suitable procedure to measure the effective temperature in off-equilibrium systems. We analyze the stationary current established between an off-equilibrium syste…
