Ising Models of Cooperativity in Muscle Contraction
Elaheh Saadat, Matthieu Caruel, Stefano Gherardini +6
Regulation of contraction in striated muscle is controlled by a dual mechanism involving both thin filaments containing actin and thick filaments containing myosin. The thin filame…
Smart Walkers in Discrete Space
Gianluca Peri, Lorenzo Buffoni, Giacomo Chiti +4
We study the statistical properties of trainable agents moving in discrete space. After introducing the mathematical framework, we first analyze the dynamics of two completely rand…
Mean-field theory of the DNLS equation at positive and negative absolute temperatures
Michele Giusfredi, Stefano Iubini, Antonio Politi +1
The Discrete Non Linear Schrödinger (DNLS) model, due to the existence of two conserved quantities, displays an equilibrium transition between a homogeneous phase at positive absol…
Metastability in the diluted parallel Ising model
Franco Bagnoli, Tommaso Matteuzzi
We present some considerations about the parallel implementations of the kinetic (Monte Carlo) version of the Ising model. In some cases the equilibrium distribution of the paralle…
Infinite-temperature thermostats by energy localization in a nonequilibrium setup
Michele Giusfredi, Stefano Iubini, Antonio Politi +1
Some lattice models having two conservation laws may display an equilibrium phase transition from a homogeneous (positive temperature - PT) to a condensed (negative temperature) ph…
Localization and "classical entanglement'' in the Discrete Non-Linear Schrödinger Equation
Martina Giachello, Stefano Iubini, Roberto Livi +1
We perform a detailed numerical study of the very peculiar thermodynamic properties of the localized high-energy phase of the Discrete Non-Linear Schrödinger Equation (DNLSE). A nu…
Helicity modulus in the bilayer XY model by worm algorithm
A. Masini, A. Cuccoli, A. Rettori +2
The behaviour of the helicity modulus has been frequently employed to investigate the onset of the topological order characterizing the low-temperature phase of the two-dimensional…
Localization in boundary-driven lattice models
Michele Giusfredi, Stefano Iubini, Paolo Politi
Several systems display an equilibrium condensation transition, where a finite fraction of a conserved quantity is spatially localized. The presence of two conservation laws may in…
Liquid-liquid transition in a Bose fluid near collapse
Saverio Moroni, Fabio Cinti, Massimo Boninsegni +2
Discovering novel emergent behavior in quantum many-body systems is a main objective of contemporary research. In this paper, we explore the effects on phases and phase transitions…
Symplectic quantization III: Non-relativistic limit
Giacomo Gradenigo, Roberto Livi, Luca Salasnich
First of all we shortly illustrate how the symplectic quantization scheme [Gradenigo and Livi, 2021] can be applied to a relativistic field theory with self-interaction. Taking ins…
Generalized Landauer bound from absolute irreversibility
Lorenzo Buffoni, Francesco Coghi, Stefano Gherardini
In this work, we introduce a generalization of the Landauer bound for erasure processes that stems from absolutely irreversible dynamics. Assuming that the erasure process is carri…
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…
Role of the single-particle dynamics in the transverse current autocorrelation function of a liquid metal
Eleonora Guarini, Ubaldo Bafile, Daniele Colognesi +6
A very recent simulation study of the transverse current autocorrelation of the Lennard-Jones fluid revealed, as expected, that this function can be perfectly described within the…
Relaxation dynamics and finite-size effects in a simple model of condensation
Gabriele Gotti, Stefano Iubini, Paolo Politi
We consider a simple, purely stochastic model characterized by two conserved quantities (mass density and energy density ) which is known to display a condensation transitio…
Convergence of the Integral Fluctuation Theorem estimator for nonequilibrium Markov systems
Francesco Coghi, Lorenzo Buffoni, Stefano Gherardini
The Integral Fluctuation Theorem for entropy production (IFT) is among the few equalities that are known to be valid for physical systems arbitrarily driven far from equilibrium. M…
Global topological synchronization on simplicial and cell complexes
Timoteo Carletti, Lorenzo Giambagli, Ginestra Bianconi
Topological signals, i.e., dynamical variables defined on nodes, links, triangles, etc. of higher-order networks, are attracting increasing attention. However the investigation of…
Condensation induced by coupled transport processes
Gabriele Gotti, Stefano Iubini, Paolo Politi
Several lattice models display a condensation transition in real space when the density of a suitable order parameter exceeds a critical value. We consider one of such models with…
Topological Theory of Phase Transitions
Matteo Gori, Roberto Franzosi, Giulio Pettini +1
The investigation of the Hamiltonian dynamical counterpart of phase transitions, combined with the Riemannian geometrization of Hamiltonian dynamics, has led to a preliminary formu…
Onset of two collective excitations in the transverse dynamics of a simple fluid
Eleonora Guarini, Martin Neumann, Alessio De Francesco +5
A thorough analysis of the transverse current autocorrelation function obtained by molecular dynamics simulations of a dense Lennard-Jones fluid reveals that even such a simple sys…
Metastability of synchronous and asynchronous dynamics
Emilio N. M. Cirillo, Vanessa Jacquier, Cristian Spitoni
Metastability is an ubiquitous phenomenon in nature, which interests several fields of natural sciences. Its description in the framework of thermodynamics and statistical mechanic…
Prestrain-induced contraction in 1D random elastic chains
Ihusan Adam, Franco Bagnoli, Duccio Fanelli +2
Prestrained elastic networks arise in a number of biological and technological systems ranging from the cytoskeleton of cells to tensegrity structures. To understand the response o…
Violent relaxation in the Hamiltonian mean field model: II. Non-equilibrium phase diagrams
Alessandro Santini, Guido Giachetti, Lapo Casetti
A classical long-range-interacting -particle system relaxes to thermal equilibrium on time scales growing with ; in the limit such a relaxation time diverges. H…

Spontaneous fluctuation-symmetry breaking and the Landauer principle
Lorenzo Buffoni, Michele Campisi
We study the problem of the energetic cost of information erasure by looking at it through the lens of the Jarzynski equality. We observe that the Landauer bound, $\langle W \rangl…
