Nonlinear dynamics and fluctuations in biological systems (Habilitation thesis)
Benjamin M. Friedrich
The present habilitation thesis in theoretical biological physics addresses two central dynamical processes in cells and organisms: (i) active motility and motility control and (ii…
In-phase and anti-phase flagellar synchronization by basal coupling
G. S. Klindt, C. Ruloff, C. Wagner +1
We present a theory of flagellar synchronization in the green alga Chlamydomonas, using full treatment of flagellar hydrodynamics. We find that two recently proposed synchronizatio…
The load-response of the flagellar beat
Gary S. Klindt, Christian Ruloff, Christian Wanger +1
Cilia and flagella exhibit regular bending waves that perform mechanical work on the surrounding fluid, to propel cellular swimmers and pump fluids inside organisms. Here, we quant…
Hydrodynamic synchronization of flagellar oscillators
B. M. Friedrich
We survey the theory synchronization in collections of noisy oscillators. This framework is applied to flagellar synchronization by hydrodynamic interactions. The time-reversibilit…
Flagellar swimmers oscillate between pusher- and puller-type swimming
Gary S. Klindt, Benjamin M. Friedrich
Self-propulsion of cellular microswimmers generates flow signatures, commonly classified as pusher- and puller-type, which characterize hydrodynamic interactions with other cells o…
Active phase and amplitude fluctuations of flagellar beating
Rui Ma, Gary S. Klindt, Ingmar H. Riedel-Kruse +2
The eukaryotic flagellum beats periodically, driven by the oscillatory dynamics of molecular motors, to propel cells and pump fluids. Small, but perceivable fluctuations in the bea…
Cell body rocking is a dominant mechanism for flagellar synchronization in a swimming alga
Veikko Geyer, Frank Jülicher, Jonathon Howard +1
The unicellular green algae Chlamydomonas swims with two flagella, which can synchronize their beat. Synchronized beating is required to swim both fast and straight. A long-standin…
A three-sphere swimmer for flagellar synchronization
Katja Polotzek, Benjamin M. Friedrich
In a recent letter (Friedrich et al., Phys. Rev. Lett. 109:138102, 2012), a minimal model swimmer was proposed that propels itself at low Reynolds numbers by a revolving motion of…
