Quo vadis, stochastic thermodynamics?
Jan Korbel, Artemy Kolchinsky, Sarah A. M. Loos +4
Stochastic thermodynamics is a framework for describing non-equilibrium processes at the level of fluctuating trajectories, where the state of a system evolves as a stochastic time…
Finite-time transitions in optimal control and non-equilibrium relaxation
Jan Meibohm, Samuel Monter, Sarah A. M. Loos +1
We theoretically and experimentally study finite-time optimal control of a colloidal particle steered through a spatially inhomogeneous environment, modeled by a position-dependent…
Energy-Efficient Control of Interacting Microscopic Systems: When Longer Paths Save Energy
Samuel Monter, Lars T. Stutzer, Sarah A. M. Loos +1
We experimentally and theoretically study the thermodynamically optimal control of interacting multiple-particle systems, focusing on collections of colloidal particles individuall…
Extracting work from hidden degrees of freedom
Lokesh Muruga, Felix Ginot, Sarah A. M. Loos +1
Thermodynamics establishes that information acquired through measurement can be converted into work, as exemplified by Maxwell's demon and Szilard engines. Most experimental realiz…
Active particles in moving traps: minimum work protocols and information efficiency of work extraction
Janik Schüttler, Rosalba Garcia-Millan, Michael E. Cates +1
We revisit the elementary problem of moving a particle in a harmonic trap in finite time with minimal work cost, and extend it to the case of an active particle. By comparing the G…
Optimal closed-loop control of active particles and a minimal information engine
Rosalba Garcia-Millan, Janik Schüttler, Michael E. Cates +1
We study the elementary problem of moving an active particle by a trap with minimum work input. We show analytically that (open-loop) optimal protocols are not affected by activity…
