Correlated continuous-time random walk in the velocity field: the role of velocity and weak asymptotics

Within the framework of a space-time correlated continuous-time random walk model, anomalous diffusion of particles moving in the velocity field is studied in this paper. The weak asymptotic form ω ( t ) ∼ t −(1+ α ) , 1 < α < 2 for large t , is considered to be the waiting time distribution....
