The large deviation approach to statistical mechanics

H Touchette - Physics Reports, 2009 - Elsevier
The theory of large deviations is concerned with the exponential decay of probabilities of
large fluctuations in random systems. These probabilities are important in many fields of …

Statistical mechanics and dynamics of solvable models with long-range interactions

A Campa, T Dauxois, S Ruffo - Physics Reports, 2009 - Elsevier
For systems with long-range interactions, the two-body potential decays at large distances
as V (r)∼ 1/rα, with α≤ d, where d is the space dimension. Examples are: gravitational …

[图书][B] Physics of long-range interacting systems

A Campa, T Dauxois, D Fanelli, S Ruffo - 2014 - books.google.com
This book deals with an important class of many-body systems: those where the interaction
potential decays slowly for large inter-particle distances; in particular, systems where the …

Phase transitions and configuration space topology

M Kastner - Reviews of Modern Physics, 2008 - APS
Equilibrium phase transitions may be defined as nonanalytic points of thermodynamic
functions, eg, of the canonical free energy. Given a certain physical system, it is of interest to …

Gaussian concentration bound and ensemble equivalence in generic quantum many-body systems including long-range interactions

T Kuwahara, K Saito - Annals of Physics, 2020 - Elsevier
This work explores fundamental statistical and thermodynamic properties of short-and long-
range-interacting systems. The purpose of this study is twofold. Firstly, we rigorously prove …

Nonequivalence of ensembles for long-range quantum spin systems in optical lattices

M Kastner - Physical review letters, 2010 - APS
Motivated by the anisotropic long-range nature of the interactions between cold dipolar
atoms or molecules in an optical lattice, we study the anisotropic quantum Heisenberg …

Inequivalence of nonequilibrium path ensembles: the example of stochastic bridges

J Szavits-Nossan, MR Evans - Journal of Statistical Mechanics …, 2015 - iopscience.iop.org
We study stochastic processes in which the trajectories are constrained so that the process
realises a large deviation of the unconstrained process. In particular we consider stochastic …

Crossover in density profiles of confined particles in power-law models with finite range of interaction

S Santra, A Kundu - arXiv preprint arXiv:2308.12124, 2023 - arxiv.org
We consider a classical system of $ N $ particles confined in a harmonic trap in one
dimension. The pairwise interaction potential between two particles separated by a distance …

Concavity, response functions and replica energy

A Campa, L Casetti, I Latella, A Pérez-Madrid, S Ruffo - Entropy, 2018 - mdpi.com
In nonadditive systems, like small systems or like long-range interacting systems even in the
thermodynamic limit, ensemble inequivalence can be related to the occurrence of negative …

Nonanalyticities of the entropy induced by saddle points of the potential energy landscape

M Kastner, O Schnetz, S Schreiber - Journal of Statistical …, 2008 - iopscience.iop.org
The relation between saddle points of the potential of a classical many-particle system and
the analyticity properties of its Boltzmann entropy is studied. For finite systems, each saddle …
