Extended fluctuation-dissipation theorem for soft matter in stationary flow
Extended fluctuation-dissipation theorem for soft matter in stationary flow
For soft matter systems strongly driven by stationary flow, we discuss an extended fluctuation-dissipation theorem (FDT). Beyond the linear-response regime, the FDT for the stress acquires an additional contribution involving the observable that is conjugate to the strain rate with respect to the dissipation function. This extended FDT is evaluated …
