QCD equation of state at finite chemical potentials for relativistic nuclear collisions [PDF]
International Journal of Modern Physics A, 2021 We review the equation of state of QCD matter at finite densities. We discuss the construction of the equation of state with net baryon number, electric charge, and strangeness using the results of lattice QCD simulations and hadron resonance gas models.

An improved equation of state for air plasma simulations [PDF]
The Physics of Fluids, 2021 This work is concerned with the development of a novel, accurate equation of state for describing partially ionized air plasma in local thermodynamic equilibrium. One key application for this new equation of state is the simulation of lightning strike on

Emergence of the Gambier equation in cosmology [PDF]
Modern Physics Letters A, 2023, 2023 We show how the Gambier equation arises in connection to Friedmann-Lema$\mbox{\^{i}}$tre-Robertson-Walker (FLRW) cosmology and a Dark Matter equation of state. Moreover, we provide a correspondence between the Friedmann equations and the Gambier equations that possess the Painlev$\acute{\mbox{e}}$ property in $2+1$ dimensions.

Masses, Radii, and the Equation of State of Neutron Stars [PDF]
, 2016 We summarize our current knowledge of neutron-star masses and radii. Recent instrumentation and computational advances have resulted in a rapid increase in the discovery rate and precise timing of radio pulsars in binaries in the past few years, leading ...

An inflationary equation-of-state
International Journal of Modern Physics D, 2023 In this paper, we have studied inflationary paradigm through an inflationary equation-of-state. With a single parameter equation-of-state as a function of the scalar field responsible for accelerated expansion, we find an observationally viable model satisfying all the constraints as laid down by the recent observations.

Radial Oscillations in Neutron Stars from Unified Hadronic and Quarkyonic Equation of States
Galaxies, 2023 We study radial oscillations in non-rotating neutron stars by considering the unified equation of states (EoSs), which support the 2 M⊙ star criterion.

On the invariant region for compressible Euler equations with a general equation of state [PDF]
Communications on Pure and Applied Analysis, 2021, 20(7&8):
2751-2763, 2022 The state space for solutions of the compressible Euler equations with a general equation of state is examined. An arbitrary equation of state is allowed, subject only to the physical requirements of thermodynamics. An invariant region of the resulting Euler system is identified and the convexity property of this region is justified by using only very ...

Multimessenger constraints on the neutron-star equation of state and the Hubble constant
Science, 2020 A combined multimessenger analysis Neutron stars are stellar remnants with densities greater than that of an atomic nucleus. The properties of matter under such extreme conditions are poorly understood and inaccessible to terrestrial laboratories ...
