Title: Higher-order memory and inertia effects in Onsager-Machlup theory 
of stochastic fluctuations

Abstract:
In two seminal papers [1, 2] Onsager and Machlup introduced the 
celebrated theory of stochastic fluctuations for thermodynamic systems.
Whereas their first contribution [1] proposes a variational principle
that leads to a simple Langevin dynamics of first order in time, the
second [2] extends this formalism to more complex systems that include
inertia and memory effects via a second-order stochastic equation. I
will present a higher-order generalization of the Onsager-Machlup theory
and discuss its applications to equilibrium and nonequilibrium dynamics
of currents.
