Discontinuous Thinning in Active Microrheology of Soft Complex Matter
R. Wulfert, U. Seifert, T. Speck
Employing theory and numerical simulations, we demonstrate discontinuous force thinning due to the motion of an external probe in a host medium, which we approximate as structurele…
An autonomous and reversible Maxwell's demon
Andre Cardoso Barato, Udo Seifert
Building on a model introduced by Mandal and Jarzynski [Proc. Natl. Acad. Sci. U. S. A., {\bf 109}, (2012) 11641], we present a simple version of an autonomous reversible Maxwell's…
Noninvasive Measurement of Dissipation in Colloidal Systems
Boris Lander, Jakob Mehl, Valentin Blickle +2
According to Harada and Sasa [Phys. Rev. Lett. 95, 130602 (2005)], heat production generated in a non-equilibrium steady state can be inferred from measuring response and correlati…
Extracting work from a single heat bath through feedback
D. Abreu, U. Seifert
Work can be extracted from a single heat bath if additional information is available. For the paradigmatic case of a Brownian particle in a harmonic potential, whose position has b…
Mobility and Diffusion of a Tagged Particle in a Driven Colloidal Suspension
Boris Lander, Udo Seifert, Thomas Speck
We study numerically the influence of density and strain rate on the diffusion and mobility of a single tagged particle in a sheared colloidal suspension. We determine independentl…
Efficiency of molecular motors at maximum power
Tim Schmiedl, Udo Seifert
Molecular motors transduce chemical energy obtained from hydrolizing ATP into mechanical work exerted against an external force. We calculate their efficiency at maximum power outp…
