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…
Using the fluctuation-dissipation theorem for nonconservative forces
Kiryl Asheichyk, Matthias Krüger
An equilibrium system which is perturbed by an external potential relaxes to a new equilibrium state, a process obeying the fluctuation-dissipation theorem. In contrast, perturbing…
Response of active Brownian particles to shear flow
Kiryl Asheichyk, Alexandre P. Solon, Christian M. Rohwer +1
We study the linear response of interacting active Brownian particles in an external potential to simple shear flow. Using a path integral approach, we derive the linear response o…
Heat radiation and transfer in confinement
Kiryl Asheichyk, Matthias Krüger
Near-field heat radiation and transfer are rich in various exciting effects, in particular, regarding the amplification due to the geometrical configuration of the system. In this…
