Being heterogeneous is disadvantageous: Brownian non-Gaussian searches
Diffusing diffusivity models, polymers in the grand canonical ensemble and polydisperse,
and continuous-time random walks all exhibit stages of non-Gaussian diffusion. Is non …

Two-states Brownian particle in a Harmonic Potential
We study the behaviour of a Brownian particle in the overdamped regime in the presence of
a harmonic potential, assuming its diffusion coefficient to randomly jump between two …
