Description
We develop a weak noise scheme addressing problems
in non equilibrium statistical physics. The evaluation
of transition probabilities is expressed in terms of
a classical action in a Hamiltonian framework.
We consider as examples: 1) free brownian particle, 2)
over damped particle in harmonic potential, 3) noisy finite
singularity, and 4) the Kardar-Parisi-Zhang equation for a
growing interface.
