Thermodynamics, Statistical Mechanics and Entropy

open access: yesEntropy, 2017
The proper definition of thermodynamics and the thermodynamic entropy is discussed in the light of recent developments. The postulates for thermodynamics are examined critically, and some modifications are suggested to allow for the inclusion of long ...

Some speculations about local thermalization of nonequilibrium extended quantum systems

open access: yesCondensed Matter Physics, 2023
We discuss the possibility of defining an emergent local temperature in extended quantum many-body systems evolving out of equilibrium. For the most simple case of free-fermionic systems, we give an explicit formula for the effective temperature in the ...

Signal Statistical Mechanics

open access: yesComputation
We are interested in determining the physics bound for the detection of signals in modern digital radio frequency (RF) hardware. Classical signal theory (Kalman filters) requires that the signal-to-noise power ratio (SNR) >10, but this is not the physics

Statistical Mechanics of Voting [PDF]

open access: yesPhysical Review Letters, 1998
Decision procedures aggregating the preferences of multiple agents can produce cycles and hence outcomes which have been described heuristically as `chaotic'. We make this description precise by constructing an explicit dynamical system from the agents' preferences and a voting rule. The dynamics form a one dimensional statistical mechanics model; this

Work statistics in stochastically driven systems

open access: yesNew Journal of Physics, 2014
We identify the conditions under which a stochastic driving that induces energy changes into a system coupled with a thermal bath can be treated as a work source.

Geometrization of statistical mechanics

open access: yesProceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1999
Classical and quantum statistical mechanics are cast here in the language of projective geometry to provide a unified geometrical framework for statistical physics. After reviewing the Hilbert space formulation of classical statistical thermodynamics, we introduce projective geometry as a basis for analysing probabilistic aspects of statistical physics.

Is Kaniadakis κ-generalized statistical mechanics general?

open access: yesPhysics Letters B, 2023
In this Letter we introduce some field-theoretic approach for computing the critical properties of systems undergoing continuous phase transitions governed by the κ-generalized statistics, namely κ-generalized statistical field theory.

Typicality and the Approach to Equilibrium in Boltzmannian Statistical Mechanics [PDF]

open access: yes, 2009
Systems prepared in a non-equilibrium state approach, and eventually reach, equilibrium. Why do they do so? An important contemporary version of the Boltzmannian approach to statistical mechanics answers this question in terms of typicality.

Statistical mechanics of networks [PDF]

open access: yesPhysical Review E, 2004
We study the family of network models derived by requiring the expected properties of a graph ensemble to match a given set of measurements of a real-world network, while maximizing the entropy of the ensemble. Models of this type play the same role in the study of networks as is played by the Boltzmann distribution in classical statistical mechanics ...
