Motility-induced clustering of active particles under soft confinement
Timo Knippenberg, Ashreya Jayaram, Thomas Speck +1
We investigate the structural and dynamic properties of active Brownian particles (APs) confined within a soft annulus-shaped channel. Depending on the strength of the confinement…
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…
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…
Jarzynski Relation, Fluctuation Theorems, and Stochastic Thermodynamics for Non-Markovian Processes
Thomas Speck, Udo Seifert
We prove the Jarzynski relation for general stochastic processes including non-Markovian systems with memory. The only requirement for our proof is the existence of a stationary st…
Distribution of Entropy Production for a Colloidal Particle in a Nonequilibrium Steady State
T. Speck, V. Blickle, C. Bechinger +1
For a colloidal particle driven by a constant force across a periodic potential, we investigate the distribution of entropy production both experimentally and theoretically. For sh…
Measurement of Stochastic Entropy Production
C. Tietz, S. Schuler, T. Speck +2
Using fluorescence spectroscopy we directly measure entropy production of a single two-level system realized experimentally as an optically driven defect center in diamond. We expl…
