The effective temperature

By L. Cugliandolo. 2011

267 citations recorded by the source corpus.

This review presents the effective temperature notion as defined from the deviations from the equilibrium fluctuation–dissipation theorem in out-of-equilibrium systems with slow dynamics. The thermodynamic meaning of this quantity is discussed in detail. Analytic, numeric and experimental measurements are surveyed. Open issues are mentioned.

Pressure is not a state function for generic active fluids (2014, methodology): “Recall, however, that equation (2) describes particles moving on, or through, amedium that absorbsmomentum, and this net force is exactly cancelled by the momentum exchange with the support.”
