Non-Gaussian statistics of concentration fluctuations in free liquid diffusion
Marco Bussoletti, Mirko Gallo, Amir Jafari +1
We show that the three-point skewness of concentration fluctuations is non-vanishing in free liquid diffusion, even in the limit of vanishingly small mean concentration gradients.…

Emergence of long-range non-equilibrium correlations in free liquid diffusion
Marco Bussoletti, Mirko Gallo, Amir Jafari +1
It is experimentally well-established that non-equilibrium long-range correlations of concentration fluctuations appear in free diffusion of a solute in a solvent, but it remains u…
