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…
Finite-size scaling at the edge of disorder in a time-delay Vicsek model
Viktor Holubec, Daniel Geiss, Sarah A. M. Loos +2
Living many-body systems often exhibit scale-free collective behavior reminiscent of thermal critical phenomena. But their mutual interactions are inevitably retarded due to inform…
Brownian Thermometry Beyond Equilibrium
Daniel Geiss, Klaus Kroy
Since Albert Einstein's seminal 1905-paper on Brownian motion, the temperature of fluids and gases of known viscosity can be deduced from observations of the fluctuations of small…
