Extended Fluctuation-Dissipation Theorem for Soft Matter in Stationary Flow
Thomas Speck, Udo Seifert
For soft matter systems strongly driven by stationary flow, we discuss an extended fluctuation-dissipation theorem (FDT). Beyond the linear response regime, the FDT for the stress…
Elastic capsules in shear flow: Analytical solutions for constant and time-dependent shear rates
Steffen Kessler, Reimar Finken, Udo Seifert
We investigate the dynamics of microcapsules in linear shear flow within a reduced model with two degrees of freedom. In previous work for steady shear flow, the dynamic phases of…
Role of External Flow and Frame Invariance in Stochastic Thermodynamics
Thomas Speck, Jakob Mehl, Udo Seifert
For configurational changes of soft matter systems affected or caused by external hydrodynamic flow, we identify applied work, exchanged heat, and entropy change on the level of a…
Curvature-coupling dependence of membrane protein diffusion coefficients
Stefan M. Leitenberger, Ellen Reister-Gottfried, Udo Seifert
We consider the lateral diffusion of a protein interacting with the curvature of the membrane. The interaction energy is minimized if the particle is at a membrane position with a…
Fluctuation spectra of free and supported membrane pairs
Rolf-Juergen Merath, Udo Seifert
Fluctuation spectra of fluid compound membrane systems are calculated. The systems addressed contain two (or more) almost parallel membranes that are connected by harmonic tethers…
Hybrid simulations of lateral diffusion in fluctuating membranes
Ellen Reister-Gottfried, Stefan M. Leitenberger, Udo Seifert
In this paper we introduce a novel method to simulate lateral diffusion of inclusions in a fluctuating membrane. The regarded systems are governed by two dynamic processes: the hei…
