Brownian systems perturbed by mild shear: Comparing response relations
Kiryl Asheichyk, Matthias Fuchs, Matthias Krüger
We present a comprehensive study of the linear response of interacting underdamped Brownian particles to simple shear flow. We collect six different routes for computing the respon…
Near field propulsion forces from nonreciprocal media
David Gelbwaser-Klimovsky, Noah Graham, Mehran Kardar +1
Arguments based on symmetry and thermodynamics may suggest the existence of a ratchet-like lateral Casimir force between two plates at different temperatures and with broken invers…
Spatially resolved atomic-scale friction: Theory and Simulation
Miru Lee, Richard L. C. Vink, Matthias Krüger
We analyze the friction force exerted on a small probe particle sliding over an atomic-scale surface by means of a Green-Kubo relation and classical Molecular Dynamics simulations.…
Activated diffusiophoresis
Christian M. Rohwer, Mehran Kardar, Matthias Krüger
Perturbations of fluid media can give rise to non-equilibrium dynamics, which may in turn cause motion of immersed inclusions. We consider perturbations ("activations") that are lo…
