Restoring a fluctuation-dissipation theorem in a nonequilibrium steady state
II. Institut für Theoretische Physik, Universität Stuttgart - 70550 Stuttgart, Germany
Accepted: 1 March 2006
In a nonequilibrium steady state, the violation of the fluctuation-dissipation theorem (FDT) is connected to breaking detailed balance. For the velocity correlations of a driven colloidal particle we calculate an explicit expression of the FDT violation. The equilibrium form of the FDT can be restored by measuring the velocity with respect to the local mean velocity.
