Nonlinear driven diffusive systems with dissipation: Fluctuating hydrodynamics
(American Physical Society, 2012)
We consider a general class of nonlinear diffusive models with bulk dissipation and boundary driving and derive its hydrodynamic description in the large size limit. Both the average macroscopic behavior and the fluctuating ...

Kovacs-like memory effect in athermal systems: Linear response analysis
(Multidisciplinary Digital Publishing Institute (MDPI), 2017)
We analyze the emergence of Kovacs-like memory effects in athermal systems within the linear response regime. This is done by starting from both the master equation for the probability distribution and the equations for ...

When the Hotter Cools More Quickly: Mpemba Effect in Granular Fluids
(American Physical Society, 2017)
Under certain conditions, two samples of fluid at different initial temperatures present a counterintuitive behavior known as the Mpemba effect: it is the hotter system that cools sooner. Here, we show that the Mpemba ...

Sawtooth patterns in force-extension curves of biomolecules: An equilibrium-statistical-mechanics theory
(American Physical Society, 2013)
We analyze the force-extension curve for a general class of systems, which are described at the mesoscopic level by a free energy depending on the extension of its components. Similarly to what is done in real experiments, the ...

Kovacs-Like Memory Effect in Driven Granular Gases
(American Physical Society, 2014-05-14)
While memory effects have been reported for dense enough disordered systems such as glasses, we show here by a combination of analytical and simulation techniques that they are also intrinsic to the dynamics of dilute ...

Ripples in a string coupled to Glauber spins
(American Physical Society, 2012)
Each oscillator in a linear chain (a string) interacts with a local Ising spin in contact with a thermal bath. These spins evolve according to Glauber dynamics. Below a critical temperature, there appears an equilibrium ...

Relevance of the Speed and Direction of Pulling in Simple Modular Proteins
(American Chemical Society, 2018)
A theoretical framework capable of predicting the first unit that unfolds in pulled modular proteins has been recently introduced, for “fast enough” pulling velocities. Within this picture, we investigate the unfolding ...

Protein unfolding and refolding as transitions through virtual states
(IOP Publishing Ltd., 2014-10)
Single-molecule atomic force spectroscopy probes elastic properties of titin, ubiquitin and other relevant proteins. We explain bioprotein folding dynamics under both length- and force-clamp by modeling polyprotein modules ...

Memory effect in uniformly heated granular gases
(American Physical Society, 2014)
We evidence a Kovacs-like memory effect in a uniformly driven granular gas. A system of inelastic hard particles, in the low density limit, can reach a nonequilibrium steady state when properly forced. By following a ...

Kovacs effect in the one-dimensional Ising model: A linear response analysis
(American Physical Society, 2014)
We analyze the so-called Kovacs effect in the one-dimensional Ising model with Glauber dynamics. We consider small enough temperature jumps, for which a linear response theory has been recently derived. Within this theory, ...
