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 ...

Statistical Mechanics of Steiner trees [PDF]

open access: yes, 2008
The Minimum Weight Steiner Tree (MST) is an important combinatorial optimization problem over networks that has applications in a wide range of fields. Here we discuss a general technique to translate the imposed global connectivity constrain into many ...

Thermodynamics for Trajectories of a Mass Point [PDF]

open access: yes, 2014
On the basis of information theory, a new formalism of classical non-relativistic mechanics of a mass point is proposed. The particle trajectories of a general dynamical system defined on an (1+n)-dimensional smooth manifold are treated geometrically as ...

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.

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.

Generalization of Classical Statistical Mechanics to Quantum Mechanics and Stable Property of Condensed Matter

open access: yes, 2005
Classical statistical average values are generally generalized to average values of quantum mechanics, it is discovered that quantum mechanics is direct generalization of classical statistical mechanics, and we generally deduce both a new general ...

Statistical mechanics of voting

open access: yes, 1998
Decision procedures aggregating the preferences of multiple agents can produce cycles and hence outcomes which have been described heuristically as `chaotic'.

Subdynamics as a mechanism for objective description [PDF]

open access: yes, 1999
The relationship between microsystems and macrosystems is considered in the context of quantum field formulation of statistical mechanics: it is argued that problems on foundations of quantum mechanics can be solved relying on this relationship.

Statistical Mechanics Involving Fractal Temperature

open access: yesFractal and Fractional, 2019
In this paper, the Schrödinger equation involving a fractal time derivative is solved and corresponding eigenvalues and eigenfunctions are given. A partition function for fractal eigenvalues is defined.
