Asymptotics of work distributions in nonequilibrium systems — •Daniel Nickelsen and Andreas Engel — Universität Oldenburg, Germany

The asymptotic behaviour of work distributions in driven nonequilibrium systems, described by the Langevin equation with a potential V(x,t), is determined using the method of optimal fluctuations. For that purpose, the corresponding Euler-Lagrange equation together with the appropriate boundary conditions and differential equations regarding the leading pre-exponential factor are derived for an arbitrary V(x,t). The method is applied to an analytically solvable example, for more complicated examples the numeric implementation is demonstrated.
