Abstract

We consider decoupled continuous time random walk model with finite characteristic waiting time and approximate jump length variance. We take the waiting time probability distribution given by a combination of exponential and Mittag-Leffler function. Using this waiting time probability distribution we investigate diffusion behaviors for all the time. We obtain exact solutions for the first two moments and probability distribution for force-free and linear force cases. Due to the finite characteristic waiting time and jump length variance the model presents, for the forcefree case, normal diffusive behavior in the long-time limit. Further, the model can describe anomalous behavior at the intermediate times.
