International audience; In order to respond to environmental signals, cells often use small molecular circuits to transmit information about their surroundings. Recently, motivated by specific examples in signaling and gene regulation, a body of work

Out‐of‐Equilibrium Generalized Fluctuation–Dissipation Relations

Autor: Dario Villamaina, Giacomo Gradenigo, Angelo Vulpiani, Andrea Puglisi, Alessandro Sarracino

Publikováno v: Nonequilibrium Statistical Physics of Small Systems: Fluctuation Relations and Beyond

We discuss fluctuation-dissipation relations valid under general conditions even out of equilibrium. The response function is expressed in terms of unperperturbed correlation functions, where contributions peculiar to non-equilibrium can appear. Such

The self-similar expansion of a blast wave, well-studied in air, has peculiar counterparts in dense and dissipative media such as granular gases. Recent results have shown that, while the traditional Taylor-von Neumann-Sedov (TvNS) derivation is not

Transport Properties in Non-Equilibrium and Anomalous Systems

Autor: Dario Villamaina

The study of fluctuations in statistical physics has a long history, and a general theory is well established, connecting fluctuations to response properties of equilibrium systems. Remarkably, this framework fails as soon as some current is flowing

Estimating the principal components of correlation matrices from all their empirical eigenvectors

Autor: Dario Villamaina, Rémi Monasson

We consider the problem of estimating the principal components of a population correlation matrix from a limited number of measurement data. Using a combination of random matrix and information-theoretic tools, we show that all the eigenmodes of the

The blast caused by an intense explosion has been extensively studied in conservative fluids, where the Taylor-von Neumann-Sedov hydrodynamic solution is a prototypical example of self-similarity driven by conservation laws. In dissipative media howe

We consider an invariant random matrix model where the standard Gaussian potential is distorted by an additional single pole of order $m$. We compute the average or macroscopic spectral density in the limit of large matrix size, solving the loop equa

We review some recent results on the behavior of fluctuations in the framework of molecular motors. We present both theoretical and experimental studies, pointing out some interesting analogies shown by the large deviations of quantities such as work

Anomalous Transport and Non-Equilibrium

Autor: Dario Villamaina

Publikováno v: Transport Properties in Non-Equilibrium and Anomalous Systems ISBN: 9783319017716

This chapter the additional ingredient of anomalous diffusion, combined with non equilibrium conditions, is studied. The analysis starts with a random walk on a comb lattice, which can be analytically solvable. A detailed analysis of the “single fi
