Lévy walks with rests: Long-time analysis

Phys Rev E. 2022 Jan;105(1-1):014114. doi: 10.1103/PhysRevE.105.014114.

Abstract

In this paper we analyze the asymptotic behavior of Lévy walks with rests. Applying recent results in the field of functional convergence of continuous-time random walks we find the corresponding limiting processes. Depending on the parameters of the model, we show that in the limit we can obtain standard Lévy walk or the process describing competition between subdiffusion and Lévy flights. Some other more complicated limit forms are also possible to obtain. Finally we present some numerical results, which confirm our findings.
