Title: Control and optimization in stochastic thermodynamics
Abstract:
Control of stochastic systems is a challenging open problem in statistical
physics, with a wealth of potential applications from biology to granulates. Given a
system whose stochastic dynamics is ruled by an externally-tunable driving
parameter, the goal is to find control protocols to reach a target state in a given
finite time. Provided that this task can be accomplished, the problem of finding the
protocol that also minimises a given cost function can be addressed.
Relevant examples of control problems in stochastic thermodynamics are presented.
Specifically, the pardigmatic case of an Active Brownian Particle in harmonic
confining potential shows that control problems can also be faced in genuinely
out-of-equilibrium systems. Perspectives on open problems for underdamped dynamics
are discussed.
