Rectification of self-propelled particles by symmetric barriers

Andrey Pototsky, Aljoscha M. Hahn, Holger Stark

The motion of self-propelled particles can be rectified by asymmetric or ratchet-like periodic patterns in space. Here we show that a non-zero average drift can already be induced…

Sedimentation and polar order of active bottom-heavy particles

Katrin Wolff, Aljoscha M. Hahn, Holger Stark

Self-propelled particles in an external gravitational field have been shown to display both an increased sedimentation length and polar order even without particle interactions. He…

Measuring the convergence of Monte Carlo free energy calculations

Aljoscha M. Hahn, Holger Then

The nonequilibrium work fluctuation theorem provides the way for calculations of (equilibrium) free energy based on work measurements of nonequilibrium, finite-time processes and t…

A characteristic of Bennett's acceptance ratio method

Aljoscha Maria Hahn, Holger Then

A powerful and well-established tool for free-energy estimation is Bennett's acceptance ratio method. Central properties of this estimator, which employs samples of work values of…

Using bijective maps to improve free energy estimates

A. M. Hahn, H. Then

We derive a fluctuation theorem for generalized work distributions, related to bijective mappings of the phase spaces of two physical systems, and use it to derive a two-sided cons…
