A viscoelastic theory for ultrasound-induced intracellular streaming
Niels Gieseler, Falko Ziebert, Ulrich S. Schwarz
Ultrasound is increasingly used to control biological cells, but its multiple physical effects, including radiation force, streaming, heating, and cavitation, require theoretical f…
The Hidden Wheel-Within
Falko Ziebert, Igor M. Kulić
There is this old, eternal question: Why don't animals have wheels? In this perspective we show that they actually do. And they do so in a physically extraordinary way -- by combin…
Stochastic Path Integral for the Active Brownian Particle in a Harmonic Potential
Carsten Littek, Mike Brandt, Falko Ziebert
In this work we develop and apply a path integral formulation for the microscopic degrees of freedom obeying stochastic differential equations to an active Brownian particle (ABP)…
Reshaping and Enzymatic Activity may allow Viruses to move through the Mucus
Falko Ziebert, Kenan G. Dokonon, Igor M. Kulić
Filamentous viruses like influenza and torovirus often display systematic bends and arcs of mysterious physical origin. We propose that such viruses undergo an instability from a c…
The Physics of Self-Rolling Viruses
Pedro A. Soria Ruiz, Falko Ziebert, Igor M. Kulić
Viruses are right at the interface of inanimate matter and life. However, recent experiments [T. Sakai, et al., J.~Virol.~{\bf 92}, e01522-17 (2018)] have shown that some influenza…
