Approximating microswimmer dynamics by active Brownian motion: Energetics and efficiency
Jannik Ehrich, Marcel Kahlen
We consider the dynamics of a microswimmer and show that they can be approximated by active Brownian motion. The swimmer is modeled by coupled overdamped Langevin equations with pe…

Hidden slow degrees of freedom and fluctuation theorems: an analytically solvable model
Marcel Kahlen, Jannik Ehrich
In some situations in stochastic thermodynamics not all relevant slow degrees of freedom are accessible. Consequently, one adopts an effective description involving only the visibl…
