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…
Nonmonotonic Magnetic Friction from Collective Rotor Dynamics
Hongri Gu, Anton Lüders, Clemens Bechinger
Amontons' law postulates a monotonic relationship between frictional force and the normal load applied to a sliding contact. This empirical rule, however, fails in systems where in…
Reservoir computing from collective dynamics of active colloidal oscillators
Veit-Lorenz Heuthe, Lukas Seemann, Samuel Tovey +1
Physical reservoir computing is a computational framework that offers an energy- and computation-efficient alternative to conventional training of neural networks. In reservoir com…
