Khinchin's ergodicity and typicality in statistical mechanics

Dario Lucente, Marco Baldovin, Giacomo Gradenigo +1

The formulation of statistical mechanics in terms of ensembles, originally proposed by Gibbs, has proved to be extremely effective in describing the equilibrium state of many-parti…

Thermalization in high-dimensional systems: the (weak) role of chaos

Marco Baldovin, Marco Cattaneo, Dario Lucente +2

In their seminal work, Fermi, Pasta, Ulam and Tsingou explored the connection between statistical mechanics and dynamical properties, such as chaos and ergodicity. Even today, seve…

A mean-field theory of effective normal modes in the Fermi-Pasta-Ulam-Tsingou model

Antonio Ponno, Giacomo Gradenigo, Marco Baldovin +1

We present a non-perturbative, mean-field theory for the Fermi-Pasta-Ulam-Tsingou model with quartic interaction, capturing the quasiperiodic features shown by the system at all en…

Thermal equilibrium with generalized time-reversal symmetry

Dario Lucente, Marco Baldovin, Massimiliano Viale +1

In the study of stochastic processes, identifying the parity under time-reversal is essential to verify detailed balance, and to compute the entropy production rate (which is, othe…

On the foundations of statistical mechanics

Marco Baldovin, Giacomo Gradenigo, Angelo Vulpiani +1

Although not as wide, and popular, as that of quantum mechanics, the investigation of fundamental aspects of statistical mechanics constitutes an important research field in the bu…

Conceptual and practical approaches for investigating irreversible processes

Dario Lucente, Marco Baldovin, Fabio Cecconi +5

Current research in statistical mechanics mostly concerns the investigation of out-of-equilibrium, irreversible processes, which are ubiquitous in nature and still far from being t…

Thermalization is typical in large classical and quantum harmonic systems

Marco Cattaneo, Marco Baldovin, Dario Lucente +2

We establish an analytical criterion for dynamical thermalization within harmonic systems, applicable to both classical and quantum models. Specifically, we prove that thermalizati…

H-theorem at negative temperature: the random exchange model with bounds

Dario Lucente, Marco Baldovin, Andrea Puglisi +1

Random exchange kinetic models are widely employed to describe the conservative dynamics of large interacting systems. Due to their simplicity and generality, they are quite popula…

Self-diffusion in a strongly coupled non-neutral plasma

Marco Baldovin, Grégoire Vallet, Gaëtan Hagel +2

We propose a joint experimental and theoretical approach to measure the self-diffusion in a laser-cooled trapped ion cloud where part of the ions are shelved in a long-lived dark s…

Ergodic observables in non-ergodic systems: the example of the harmonic chain

Marco Baldovin, Raffaele Marino, Angelo Vulpiani

In the framework of statistical mechanics the properties of macroscopic systems are deduced starting from the laws of their microscopic dynamics. One of the key assumptions in this…

Control of Active Brownian Particles: An exact solution

Marco Baldovin, David Guéry-Odelin, Emmanuel Trizac

Control of stochastic systems is a challenging open problem in statistical physics, with potential applications in a wealth of systems from biology to granulates. Unlike most cases…

Extracting causation from millennial-scale climate fluctuations in the last 800 kyr

Marco Baldovin, Fabio Cecconi, Antonello Provenzale +1

The detection of cause-effect relationships from the analysis of paleoclimatic records is a crucial step to disentangle the main mechanisms at work in the climate system. Here, we…

The Many Faces of Fluctuation-Dissipation Relations Out of Equilibrium

Marco Baldovin, Lorenzo Caprini, Andrea Puglisi +2

In this paper, we offer to the reader an essential review of the theory of Fluctuation-Dissipation Relations (FDR), from the first formulations due to Einstein and Onsager, to the…

Shortcuts To Adiabaticity for Lévy processes in harmonic traps

Marco Baldovin, David Guéry-Odelin, Emmanuel Trizac

Lévy stochastic processes, with noise distributed according to a Lévy stable distribution, are ubiquitous in science. Focusing on the case of a particle trapped in an external harm…

Statistical Features of High-Dimensional Hamiltonian Systems

Marco Baldovin, Giacomo Gradenigo, Angelo Vulpiani

In this short review we propose a critical assessment of the role of chaos for the thermalization of Hamiltonian systems with high dimensionality. We discuss this problem for both…

A handy fluctuation-dissipation relation to approach generic noisy systems and chaotic dynamics

Marco Baldovin, Lorenzo Caprini, Angelo Vulpiani

We introduce a general formulation of the fluctuation-dissipation relations (FDR) holding also in far-from-equilibrium stochastic dynamics. A great advantage of this version of the…

Response and flux of information in extended non-equilibrium dynamics

Camilla Sarra, Marco Baldovin, Angelo Vulpiani

It is well known that entropy production is a proxy to the detection of non-equilibrium, i.e. of the absence of detailed balance; however, due to the global character of this quant…

Statistical Mechanics of Systems with Negative Temperature

Marco Baldovin, Stefano Iubini, Roberto Livi +1

Do negative absolute temperatures matter physics and specifically Statistical Physics? We provide evidence that we can certainly answer positively to this vexata quaestio. The grea…

Understanding causation via correlations and linear response theory
