Steady-state, effective-temperature dynamics in a glassy material.
We present a shear-transformation-zone (STZ)-based analysis of numerical simulations by Haxton and Liu [Phys. Rev. Lett. 99, 195701 (2007)]. The extensive Haxton and Liu (HL) data sharply test the basic assumptions of the STZ theory, especially the central role played by the effective disorder temperature as a dynamical state variable. We find that the theory survives these tests, and that the ...
متن کاملEffective temperatures from the fluctuation-dissipation measurements in soft glassy materials
We have investigated the validity of the fluctuation-dissipation theorem (FDT) and the applicability of the concept of effective temperature in a number of non-equilibrium soft glassy materials. Using a combination of passive and active microrheology to measure displacement fluctuations and the mechanical response function of probe particles embedded in the materials, we have directly tested th...

Communication: Effective temperature and glassy dynamics of active matter.
A systematic expansion of the many-body master equation for active matter, in which motors power configurational changes as in the cytoskeleton, is shown to yield a description of the steady state and responses in terms of an effective temperature. The effective temperature depends on the susceptibility of the motors and a Peclet number which measures their strength relative to thermal Brownian...
متن کاملGlassy dynamics in the HMF model
We discuss the glassy dynamics recently found in the meta-equilibrium quasi-stationary states (QSS) of the HMF model. The relevance of the initial conditions and the connection with Tsallis nonextensive thermostatistics is also addressed. c © 2004 Elsevier B.V. All rights reserved. PACS: 05.50.+q; 05.70.Fh; 64.60.Fr
