Variable inflaton equation-of-state and reheating [PDF]
International Journal of Modern Physics A, 2021 We explore the consequences of a time-dependent inflaton equation-of-state (EoS) parameter in the context of the post-inflationary perturbative Boltzmann reheating.

Frontiers in Earth Science, 2022 The pyrope (Prp)–almandine (Alm) solid solutions are the most fundamental garnet components on the Earth, and both the quartz inclusions in garnet (QuiG) barometry and the garnet inclusions in diamond barometry need to be constrained by the thermoelastic

A Prior Derivation and Local Existence of Classical Solutions for the Relativistic Euler Equations with Logarithmic Equation of State [PDF]
arXiv, 2021 In this paper, from an investigation of a symmetric hyperbolic system, a prior derivation of the logarithm equation of state is provided. Through a diffeomorphism transforming the classical Euler equations to the symmetric hyperbolic system, we show that the logarithm pressure co-exists with existing barotropic equations of state without applying any ...

A New Equation of State for Dense Hydrogen–Helium Mixtures [PDF]
Astrophysical Journal, 2019 We present a new equation of state (EOS) for dense hydrogen/helium mixtures that covers a range of densities from 10−8 to , pressures from 10−9 to 1013 GPa, and temperatures from 102 to 108 K.

Nuclear equation of state [PDF]
AIP Conference Proceedings, 2001 Nuclear equation of state plays an important role in the evolution of the Universe, in supernova explosions and, thus, in the production of heavy elements, and in stability of neutron stars. The equation constrains the two- and three-nucleon interactions and the quantum chromodynamics in nonperturbative regime.

Neutron Star Cooling Within the Equation of State With Induced Surface Tension
Particles, 2020 We study the thermal evolution of neutron stars described within the equation of state with induced surface tension (IST) that reproduces properties of normal nuclear matter, fulfills the proton flow constraint, provides a high-quality description of ...

Equation of State: Manhattan Project Developments and Beyond [PDF]
arXiv, 2021 The hydrodynamic response of materials under extreme conditions of pressure, temperature and strain is dependent on the equation of state of the matter in all its states of existence. The Trinity plutonium implosion device development required the Los Alamos research community to advance the understanding of equations of state further and faster than ...

New Neutron Star Equation of State with Quark–Hadron Crossover [PDF]
Astrophysical Journal, 2019 We present a much improved equation of state for neutron star matter, QHC19, with a smooth crossover from the hadronic regime at lower densities to the quark regime at higher densities. We now use the Togashi et al. equation of state, a generalization of

Ecological Modelling, 2012 The direct equivalence between ecology and thermodynamics has not been attained despite accepted thermodynamic features of the ecosystem. This article explores the homeomorphism between ecology and statistical mechanics by analysis of ruderal vegetation. In conventional thermostatistical algorithm, the pro-kinetic effect of temperature on molecules was

GW170817: Joint Constraint on the Neutron Star Equation of State from Multimessenger Observations [PDF]
, 2017 Gravitational waves detected from the binary neutron star (NS) merger GW170817 constrained the NS equation of state by placing an upper bound on certain parameters, describing the binary’s tidal interactions.
