Observation of fluctuation-dissipation-theorem violations in a structural glass

TS Grigera, NE Israeloff - Physical Review Letters, 1999 - APS
The fluctuation-dissipation theorem (FDT), connecting dielectric susceptibility and
polarization noise, was studied in glycerol below its glass transition temperature T g. Weak …

Ontological tools for geographic representation

R Casati, B Smith, A Varzi - Formal ontology in information systems, 1998 - hal.science

A far-from-equilibrium fluctuation–dissipation relation for an Ising–Glauber-like model

C Chatelain - Journal of Physics A: Mathematical and General, 2003 - iopscience.iop.org
We derive an exact expression of the response function to an infinitesimal magnetic field for
an Ising–Glauber-like model with arbitrary exchange couplings. The result is expressed in …
