Brownian motion with alternately fluctuating diffusivity: Stretched-exponential and power-law relaxation
Tomoshige Miyaguchi, Takashi Uneyama, Takuma Akimoto
We investigate Brownian motion with diffusivity alternately fluctuating between fast and slow states. We assume that sojourn-time distributions of these two states are given by exp…

Relaxation Functions of Ornstein-Uhlenbeck Process with Fluctuating Diffusivity
Takashi Uneyama, Tomoshige Miyaguchi, Takuma Akimoto
We study a relaxation behavior of an Ornstein-Uhlenbeck (OU) process with a time-dependent and fluctuating diffusivity. In this process, the dynamics of a position vector is modele…
