Exact and limit results for the CTRW in presence of drift and position dependent noise intensity
Marco Bianucci, Mauro Bologna, Riccardo Mannella
Continuous-time random walks (CTRWs) with drift and position-dependent jumps provide a general framework for describing a wide range of natural and engineered systems. We analyze t…

Universal behaviors of the multi-time correlation functions of random processes with renewal: the step noise case (the random velocity of a Lévy walk)
Marco Bianucci, Mauro Bologna, Daniele Lagomarsino-Oneto +1
Stochastic processes with renewal properties are powerful tools for modeling systems where memory effects and long-time correlations play a significant role. In this work, we study…
