Two-states Brownian particle in a Harmonic Potential
Giovanni Battista Carollo, Giuseppe Gonnella, Daniela Moretti +3
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 dist…
Being Heterogeneous Is Advantageous: Extreme Brownian Non-Gaussian Searches
Vittoria Sposini, Sankaran Nampoothiri, Aleksei Chechkin +3
Redundancy in biology may be explained by the need to optimize extreme searching processes, where one or few among many particles are requested to reach the target like in human fe…
Being heterogeneous is disadvantageous: Brownian non-Gaussian searches
Vittoria Sposini, Sankaran Nampoothiri, Aleksei Chechkin +3
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-Gauss…
Brownian non-Gaussian diffusion of self-avoiding walks
Boris Marcone, Sankaran Nampoothiri, Enzo Orlandini +2
Three-dimensional Monte Carlo simulations provide a striking confirmation to a recent theoretical prediction: the Brownian non-Gaussian diffusion of critical self-avoiding walks. A…
Brownian non-Gaussian polymer diffusion and queing theory in the mean-field limit
Sankaran Nampoothiri, Enzo Orlandini, Flavio Seno +1
We link the Brownian non-Gaussian diffusion of a polymer center of mass to a microscopic cause: the polymerization/depolymerization phenomenon occurring when the polymer is in cont…
Polymers critical point originates Brownian non-Gaussian diffusion
Sankaran Nampoothiri, Enzo Orlandini, Flavio Seno +1
We demonstrate that size fluctuations close to polymers critical point originate the non-Gaussian diffusion of their center of mass. Static universal exponents and -- depen…
