Measuring Effective Temperatures in Out-of-Equilibrium Driven Systems (2007)
We introduce and solve a model of a thermometric measurement on a driven glassy system in a stationary state. We show that a thermometer with a sufficiently slow response measures a temperature...
Effective temperature in driven vortex lattices with random pinning (2002)
Kolton, Alejandro B., Exartier, Raphael, Cugliandolo, Leticia, Dominguez, Daniel, Gronbech-Jensen, Niels
We study numerically correlation and response functions in non-equilibrium driven vortex lattices with random pinning. From a generalized fluctuation-dissipation relation we calculate an effective...
Exartier, Raphael, Cugliandolo, Leticia F.
We study numerically the time evolution of the transport properties of layered superconductors after different preparations. We show that, in accordance with recent experiments in BSCCO performed in...
A simple system with two temperatures (1999)
Exartier, Raphael, Peliti, Luca
We study the stationary nonequilibrium regime which settles in when two single-spin paramagnets each in contact with its own thermal bath are coupled. The response vs. correlation plot exhibits some...
