Journal ArticleDOI
Efficiency of a Brownian information machine
TL;DR: In this paper, the power and efficiency of two variants of a Brownian information machine operating cyclically depend on the cycle time and the precision of the positional measurements of a particle trapped in a harmonic potential.
Journal ArticleDOI
Straightening of Thermal Fluctuations in Semiflexible Polymers by Applied Tension.
TL;DR: By generalizing the internal elasticity, this work shows that tense strings exhibit qualitatively different tension profiles and propagation with an exponent of 1/2, and finds sub-diffusive propagation with a dynamical exponent of1/4.
Journal ArticleDOI
Effective rates from thermodynamically consistent coarse-graining of models for molecular motors with probe particles
Eva Zimmermann,Udo Seifert +1 more
TL;DR: A coarse-graining method is presented that maps a model comprising two coupled degrees of freedom which represent motor and probe particle to such an effective one-particle model by eliminating the dynamics of the probe particle in a thermodynamically and dynamically consistent way.
Journal ArticleDOI
Nonlinear, electrocatalytic swimming in the presence of salt
Benedikt Sabass,Udo Seifert +1 more
TL;DR: A small, bimetallic particle in a hydrogen peroxide solution that can propel itself by means of an electrocatalytic reaction is modeled for the presence of a monovalent salt, where reaction-driven proton currents induce salt ion currents.
Journal ArticleDOI
Large deviation function for the entropy production: Optimal trajectory and role of fluctuations
TL;DR: In this paper, the authors studied the large deviation function for the entropy production rate in two driven one-dimensional systems: the asymmetric random walk on a discrete lattice and Brownian motion in a continuous periodic potential, and compared two approaches: the Donsker-Varadhan theory and the Freidlin-Wentzell theory.
