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

Statistical mechanics on isoradial graphs [PDF]

open access: yes, 2010
Isoradial graphs are a natural generalization of regular graphs which give, for many models of statistical mechanics, the right framework for studying models at criticality.

Negative differential response in chemical reactions

open access: yesNew Journal of Physics, 2019
Reaction currents in chemical networks usually increase when increasing their driving affinities. But far from equilibrium the opposite can also happen. We find that such negative differential response (NDR) occurs in reaction schemes of major biological

Statistical Mechanics of Crabgrass [PDF]

open access: yesThe Annals of Probability, 1989
The authors investigate the time evolution of the contact branching particle processes on \({\mathbb{Z}}^ d/M=\{(x_ 1/M,...,x_ d/M)\}\in {\mathbb{R}}^ d,\) \(x\in {\mathbb{Z}}^ d\). The critical rate of births \(\lambda_ c(M)>0\) is introduced, \(\lambda_ c(M)=\inf \{\lambda:\) the contact process survives with positive probability\(\}\).

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 ...

Foundations of Statistical Mechanics

open access: yes, 2023
Statistical mechanics is the third pillar of modern physics, next to quantum theory and relativity theory. It aims to account for the behaviour of macroscopic systems in terms of the dynamical laws that govern their microscopic constituents and probabilistic assumptions about them.

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 glass

open access: yesJournal of Non-Crystalline Solids, 2014
AbstractThe field of glass science is quickly maturing from a purely empirical science to one built upon rigorous fundamental physics. These advancements offer an unprecedented level of understanding of the glass transition and the glassy state, as well as the ability to design new glass compositions starting at the atomic level.

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 ...
