Universal singularities of anomalous diffusion in the Richardson class
Attilio L. Stella, Aleksei Chechkin, Gianluca Teza
Inhomogeneous environments are rather ubiquitous in nature, often implying anomalies resulting in deviation from Gaussianity of diffusion processes. While sub- and superdiffusion a…
Anomalous dynamical scaling determines universal critical singularities
Attilio L. Stella, Aleksei Chechkin, Gianluca Teza
Anomalous diffusion phenomena occur on length scales spanning from intracellular to astrophysical ranges. A specific form of decay at large argument of the probability density func…
Topological disentanglement of linear polymers under tension
Michele Caraglio, Boris Marcone, Fulvio Baldovin +2
We develop a theoretical description of the topological disentanglement occurring when torus knots reach the ends of a semi-flexible polymer under tension. These include decays int…
Exact Coarse Graining Preserves Entropy Production out of Equilibrium
Gianluca Teza, Attilio L. Stella
The entropy production rate associated with broken time-reversal symmetry provides an essential characterization of nanosystems out of equilibrium, from driven colloidal particles…
Rate dependence of current and fluctuations in jump models with negative differential mobility
Gianluca Teza, Stefano Iubini, Marco Baiesi +2
Negative differential mobility is the phenomenon in which the velocity of a particle decreases when the force driving it increases. We study this phenomenon in Markov jump models w…
Role of trapping and crowding as sources of negative differential mobility
Marco Baiesi, Attilio L. Stella, Carlo Vanderzande
Increasing the crowding in an environment does not necessarily trigger negative differential mobility of strongly pushed particles. Moreover, the choice of the model, in particular…
