Age representation of Levy walks: partial density waves, relaxation and first passage time statistics
M. Giona, M. D'Ovidio, D. Cocco +2
Levy walks (LWs) define a fundamental class of finite velocity stochastic processes that can be introduced as a special case of continuous time random walks. Alternatively, there i…

Loopy Lévy flights enhance tracer diffusion in active suspensions
Kiyoshi Kanazawa, Tomohiko G. Sano, Andrea Cairoli +1
Brownian motion is widely used as a paradigmatic model of diffusion in equilibrium media throughout the physical, chemical, and biological sciences. However, many real world system…

Weak Galilean invariance as a selection principle for coarse-grained diffusive models
Andrea Cairoli, Rainer Klages, Adrian Baule
Galilean invariance is a cornerstone of classical mechanics. It states that for closed systems the equations of motion of the microscopic degrees of freedom do not change under Gal…
