Time-reversal symmetries and equilibrium-like Langevin equations
Lokrshi Prawar Dadhichi, Klaus Kroy
Graham has shown in Z. Physik B 26, 397-405 (1977) that a fluctuation-dissipation relation can be imposed on a class of non-equilibrium Markovian Langevin equations that admit a st…
Megaripple mechanics: bimodal transport ingrained in bimodal sands
Katharina Tholen, Thomas Pähtz, Hezi Yizhaq +2
Aeolian sand transport is a major process shaping landscapes on Earth and on diverse celestial bodies. Conditions favoring bimodal sand transport, with fine-grain saltation driving…
Spontaneous vortex formation by microswimmers with retarded attractions
Xiangzun Wang, Pin-Chuan Chen, Klaus Kroy +2
Collective states of inanimate particles self-assemble through physical interactions and thermal motion. Despite some phenomenological resemblance, including signatures of critical…
Signal propagation and linear response in the delay Vicsek model
Daniel Geiß, Klaus Kroy, Viktor Holubec
Retardation between sensation and action is an inherent biological trait. Here we study its effect in the Vicsek model, which is a paradigmatic swarm model. We find that: (i) a dis…
Information conduction and convection in noiseless Vicsek flocks
Daniel Geiß, Klaus Kroy, Viktor Holubec
Physical interactions generally respect certain symmetries, such as reciprocity and energy conservation, which survive in coarse grained isothermal descriptions. Active many-body s…
Superspreading and Heterogeneity in Epidemics
Klaus Kroy
Epidemic disease spreading is conventionally often modelled and analyzed by means of rate and diffusion equations, following the paradigms of well-controlled chemical reactions and…
