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…
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…
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…
Optimal Control of an Electromechanical Energy Harvester
Dario Lucente, Alessandro Manacorda, Andrea Plati +2
Many techniques originally developed in the context of deterministic control theory have been recently applied to the quest for optimal protocols in stochastic processes. Given a s…
Detecting time-irreversibility in multiscale systems: correlation and response functions in the Lorenz96 model
Niccolò Cocciaglia, Dario Lucente
Due to their relevance to geophysical systems, the investigation of multiscale systems through the lens of statistical mechanics has gained popularity in recent years. The aim of o…
