Thermodynamical instabilities of perfect fluid spheres in General Relativity [PDF]

open access: yesClassical and Quantum Gravity, 2013
For a static, perfect fluid sphere with a general equation of state, we obtain the relativistic equation of hydrostatic equilibrium, namely the Tolman-Oppenheimer-Volkov equation, as the thermodynamical equilibrium in the microcanonical, as well as the canonical, ensemble.

Thermodynamic constraints on perfect equilibrium superconducting diodes

open access: yesPhysical Review B
Superconducting diodes promise dissipationless rectification, yet equilibrium platforms without engineered junctions typically exhibit modest efficiencies. We identify a general thermodynamic origin of this behavior that is largely independent of microscopic details.

Thermodynamic properties of “near-perfect” gas

open access: yesPhysics of Plasmas
When applied thermodynamics requires simple representations of thermodynamic quantities, one often finds quantities such as pressure and the thermal energy density expressed as a monomial linear product of density and temperature power laws. This is a simple generalization of the product of density and temperature used for the perfect gas that admits a

Unique thermodynamic relationships for ΔfHo and ΔfGo for crystalline inorganic salts. I, Predicting the possible existence and synthesis of Na2SO2 and Na2SeO2 [PDF]

open access: yes, 2012
The concept that equates oxidation and pressure has been successfully utilized in explaining the structural changes observed in the M2S subnets of M2SOx (x = 3, 4) compounds (M = Na, K) when compared with the structures (room- and high-pressure phases ...

Structure of curved crystals in the thermodynamic limit and the perfect screening condition

open access: yesPhysical Review E, 2016
The dislocation and disclination density defining the structure of a crystal constrained on a general curved background is computed analytically in the thermodynamic limit, when the number of particles is arbitrarily large. It is shown that the minimum of the elastic energy, where strains are optimally close to zero, can be formulated in terms of a ...

Investigation of Cubic EOS Models for HFO-1234yf Refrigerant Used In Automotive application [PDF]

open access: yes, 2012
The need for a consistent and reliable calculation of thermodynamic property of refrigerants has been a topic of research since the past decade. This paper reports a study of various cubic equations of state (EOS) for a refrigerant to be used in ...

Thermodynamic pathways to genome spatial organization in the cell nucleus [PDF]

open access: yes, 2009
The architecture of the eukaryotic genome is characterized by a high degree of spatial organization. Chromosomes occupy preferred territories correlated to their state of activity and, yet, displace their genes to interact with remote sites in complex ...
