The peculiar response of Kelvin-Voigt chains with a free end
Rupayan Saha, Matthias Krüger
We exactly solve a model of a heterogeneous chain of overdamped, harmonically coupled particles with momentum-conserving dissipation. Despite being governed by a non-symmetric drif…
Time reversal breaking of colloidal particles in cells
Gabriel Knotz, Till M. Muenker, Timo Betz +1
We investigate signatures of broken time reversal symmetry in stochastic trajectory data, employing the previously introduced three point correlation called mean back relaxation. W…
Evaluating non-equilibrium trajectories via mean back relaxation: Dependence on length and time scales
Gabriel Knotz, Till M. Muenker, Timo Betz +1
The mean back relaxation (MBR) relates the value of a stochastic process at three different time points. It has been shown to detect broken detailed balance under certain condition…
Identities for nonlinear memory kernels
Juliana Caspers, Matthias Krüger
Perturbing a system far away from equilibrium via a time dependent protocol can formally be described by a nonlinear Volterra series expansion. Here we derive identities for the no…
Propulsion force and heat transfer for nonreciprocal nanoparticles
Laila Henkes, Kiryl Asheichyk, Matthias Krüger
We analyze heat transfer and Casimir forces involving a nonreciprocal nanoparticle. By dissecting the resulting expressions into reciprocal and nonreciprocal contributions, we find…
Evaluation of the probability current in the stochastic path integral formalism
Valentin Wilhelm, Matthias Krüger, Matthias Fuchs +1
The probability current is a vital quantity in the Fokker-Planck description of stochastic processes. It characterizes non-equilibrium stationary states and appears in linear respo…
Reflectors Tune Near-Field Thermal Transport
Yun-Chao Hao, Matthias Krüger, Mauro Antezza +3
We explore near-field thermal radiation transport in nanoparticles embedded within a multilayer slab structure, focusing on dynamic modulation of heat flux via cavity interactions.…
Nonlinear Langevin functionals for a driven probe
Juliana Caspers, Matthias Krüger
When a probe particle immersed in a fluid with nonlinear interactions is subject to strong driving, the cumulants of the stochastic force acting on the probe are nonlinear function…
Friction of a driven chain: Role of momentum conservation, Goldstone and radiation modes
Debankur Das, Richard Vink, Matthias Krüger
We analytically study friction and dissipation of a driven bead in a 1D harmonic chain, and analyze the role of internal damping mechanism as well as chain length. Specifically, we…
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…
