Neutron-Star-Merger Equation of State
Universe, 2019 In this work, we discuss the dense matter equation of state (EOS) for the extreme range of conditions encountered in neutron stars and their mergers. The calculation of the properties of such an EOS involves modeling different degrees of freedom (such as

Neural network reconstruction of the dense matter equation of state from neutron star observables [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 The Equation of State (EoS) of strongly interacting cold and hot ultra-dense QCD matter remains a major challenge in the field of nuclear astrophysics. With the advancements in measurements of neutron star masses, radii, and tidal deformabilities, from ...

Equation of state of hard-disk fluids under single-file confinement. [PDF]
Journal of Chemical Physics, 2022 The exact transfer-matrix solution for the longitudinal equilibrium properties of the single-file hard-disk fluid is used to study the limiting low- and high-pressure behaviors analytically as functions of the pore width.

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 ...

Finite-temperature equation of state with hyperons [PDF]
EPJ Web of Conferences, 2022 We present the novel finite-temperature FSU2H* equation-of-state model that covers a wide range of temperatures and lepton fractions for the conditions in proto-neutron stars, neutron star mergers and supernovae.

Lattice Study of the Equation of State of a Rotating Gluon Plasma
JETP Letters : Journal of Experimental And Theoretical Physics Letters, 2023 The effect of uniform rotation on the equation of state of gluodynamics has been studied in lattice simulation. To this end, the system has been considered in the corotating reference frame, where the rotation can be modeled as an external gravitational ...
