Generalization of the Fluctuation-Dissipation Theorem in the Off-Equilibrium Regime
Juan J. Ruiz-Lorenzo
U. Complutense de Madrid
It is well known that assuming time traslational invariance (equilibrium
regime) the fluctuation-dissipation theorem (FDT)(that relates correlation
and response functions) holds. I will present field-theoretical and
numerical arguments that support a multiplicative generalization of FDT in
the off equilibrium regime. Surprisingly it has been found that the
function that determines multiplicatively the violation of FDT can be
computed at equilibrium. Therefore I will show how to use off equilibrium
dynamics to compute equilibrium properties. As examples I will study Ising
spin glass, real glasses, diluted models and the random field ising model.
The almuerzo-seminario is
intended to be an informal seminar and an open forum for discussion.
You are wellcome to bring your own
bocata (sandwich), or coffee or tea.
