Boundary layers in stochastic thermodynamics

Physics
We study the problem of optimizing released heat or dissipated work in stochastic thermodynamics.
In the overdamped limit these functionals have singular solutions, previously interpreted as
protocol jumps. We show that a regularization, penalizing a properly defined acceleration, changes
the jumps into boundary layers of finite width. We show that in the limit of vanishing boundary
layer width no heat is dissipated in the boundary layer, while work can be done. We further give
a new interpretation of the fact that the optimal protocols in the overdamped limit are given by
optimal deterministic transport (Burgers equation).
