Information Equation of State [PDF]
Entropy, 2008 Landauer’s principle is applied to information in the universe. Once stars began forming there was a constant information energy density as the increasing proportion of matter at high stellar temperatures exactly compensated for the expanding ...

The state of the dark energy equation of state circa 2023 [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 We critically examine the state of current constraints on the dark energy (DE) equation of state (EoS) w. Our study is motivated by the observation that, while broadly consistent with the cosmological constant value w = -1, several independent probes ...

Bayesian uncertainty quantification of perturbative QCD input to the neutron-star equation of state [PDF]
Journal of High Energy Physics, 2023 The equation of state of neutron-star cores can be constrained by requiring a consistent connection to the perturbative Quantum Chromodynamics (QCD) calculations at high densities.

Chemical potential of a Lennard Jones fluid [PDF]
Serbian Astronomical Journal, 2010 The aim of this paper is to present results of analytical calculation of chemical potential of a Lennard Jones (LJ) fluid performed in two ways: by using the thermodynamical formalism and the formalism of statistical mechanics.

Equation of state and speed of sound of isospin-asymmetric QCD on the lattice [PDF]
Journal of High Energy Physics, 2022 We determine the QCD equation of state at nonzero temperature in the presence of an isospin asymmetry between the light quark chemical potentials on the lattice.

Neutron stars and the nuclear equation of state [PDF]
, 2021 We review the current status and recent progress of microscopic many-body approaches and phenomenological models, which are employed to construct the equation of state of neutron stars.

Tight multimessenger constraints on the neutron star equation of state from GW170817 and a forward model for kilonova light-curve synthesis [PDF]
Monthly notices of the Royal Astronomical Society, 2021 We present a rapid analytic framework for predicting kilonova light curves following neutron star (NS) mergers, where the main input parameters are binary-based properties measurable by gravitational wave detectors (chirp mass and mass ratio, orbital ...

Skye: A Differentiable Equation of State [PDF]
Astrophysical Journal, 2021 Stellar evolution and numerical hydrodynamics simulations depend critically on access to fast, accurate, thermodynamically consistent equations of state. We present Skye, a new equation of state for fully ionized matter.
