Discretization of continuum physics – a comparison of numerical methods from a physical point of view; pp. 145–154 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2008
For numerical calculations in continuum physics partial differential equations and the space-time are discretized. This can be done in different ways. Common approaches are finite difference methods and finite element methods, more rarely finite volume ...

Thermal Correlators in Little String Theory [PDF]

open access: yes, 2003
We calculate, using holographic duality, the thermal two-point function in finite temperature little string theory. The analysis of those correlators reveals possible instabilities of the thermal ensemble, as in previous discussions of the thermodynamics

Analysis of the thermomechanical inconsistency of some extended hydrodynamic models at high Knudsen number [PDF]

open access: yes, 2012
There are some hydrodynamic equations that, while their parent kinetic equation satisfies fundamental mechanical properties, appear themselves to violate mechanical or thermodynamic properties.

Defining the pressures of a fluid in a nanoporous, heterogeneous medium

open access: yesFrontiers in Physics, 2022
We describe the thermodynamic state of a single-phase fluid confined to a porous medium with Hill’s thermodynamics of small systems, also known as nanothermodynamics.

Phase Structure of Non-Commutative Field Theories and Spinning Brane Bound States [PDF]

open access: yes, 1999
General spinning brane bound states are constructed, along with their near-horizon limits which are relevant as dual descriptions of non-commutative field theories.

A New Entropy Function to Analyze Isentropic Processes of Ideal Gases with Variable Specific Heats

open access: yesEntropy, 2022
A new entropy function s+ is defined in terms of the existing entropy function s° and temperature as s+ = s° − R lnT to facilitate the analysis of isentropic processes of ideal gases with variable specific heats. The function s+ also makes it possible to

Improved thermodynamics of SU(2) gauge theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In this work we present the results of our investigation of the thermodynamics of SU(2) gauge theory. We employ a Symanzik improved action to reduce strongly the discretisations effects, and we use the scaling relations to take into account the finite ...

Macroscopic form of the first law of thermodynamics for an adiabatically evolving non-singular self-gravitating fluid

open access: yes, 2011
We emphasize that the pressure related work appearing in a general relativistic first law of thermodynamics should involve {\em proper volume element} rather than coordinate volume element.

The Zeroth Law of Thermodynamics and Volume-Preserving Conservative Dynamics with Equilibrium Stochastic Damping [PDF]

open access: yes, 2013
We propose a mathematical formulation of the zeroth law of thermodynamics and develop a stochastic dynamical theory, with a consistent irreversible thermodynamics, for systems possessing sustained conservative stationary current in phase space while in ...
