Wrinkling instability of vesicles in steady linear flow
Michael Levant, David Abreu, Udo Seifert +1
We present experimental observations and numerical simulations of a wrinkling instability that occurs at sufficiently high strain rates in the trembling regime of vesicle dynamics…
Fluid Vesicles in Flow
David Abreu, Michael Levant, Victor Steinberg +1
We review the dynamical behavior of giant fluid vesicles in various types of external hydrodynamic flow. The interplay between stresses arising from membrane elasticity, hydrodynam…
Noisy nonlinear dynamics of vesicles in flow
David Abreu, Udo Seifert
We present a model for the dynamics of fluid vesicles in linear flow which consistently includes thermal fluctuations and nonlinear coupling between different modes. At the transit…
Effect of thermal noise on vesicles and capsules in shear flow
David Abreu, Udo Seifert
We add thermal noise consistently to reduced models of undeformable vesicles and capsules in shear flow and derive analytically the corresponding stochastic equations of motion. We…
Efficiency of a Brownian information machine
Michael Bauer, David Abreu, Udo Seifert
A Brownian information machine extracts work from a heat bath through a feedback process that exploits the information acquired in a measurement. For the paradigmatic case of a par…
Thermodynamics of genuine non-equilibrium states under feedback control
D. Abreu, U. Seifert
For genuine non-equilibrium states that even at fixed external control parameter exhibit dissipation, we extend the Hatano-Sasa equality to processes with feedback control. The res…
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…
