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.

The influence of the equation of state on the cellular structure of gaseous detonations
The Physics of Fluids, 2021 The propagation of multidimensional gaseous detonations at elevated pressures was investigated numerically. Initial conditions at which deviations from ideal gas are expected (i.e., p0 > 2 MPa) were used to assess whether real gas effects influence their

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

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

Equation of State and Collective Dynamics
, 2005 This talk summarizes the present status of a program to quantitatively relate data from the Relativistic Heavy Ion Collider (RHIC) on collective expansion flow to the Equation of State (EOS) of hot and dense strongly interacting matter, including the ...

Low-Density Neutron Matter and the Unitary Limit
Frontiers in Physics, 2021 We review the properties of neutron matter in the low-density regime. In particular, we revise its ground state energy and the superfluid neutron pairing gap and analyze their evolution from the weak to the strong coupling regime. The calculations of the

Dark-energy equation of state: how far can we go from Λ? [PDF]
, 2006 The equation of state of dark energy is investigated to determine how much it may deviate from the equation of state of the cosmological constant (CC). Two aspects of the problem are studied: the "expansion" around the vacuum equation of state and the problem of the crossing of the cosmological constant boundary.

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.

Equation of State in Numerical Relativistic Hydrodynamics [PDF]
, 2006 Relativistic temperature of gas raises the issue of the equation of state (EoS) in relativistic hydrodynamics. We study the EoS for numerical relativistic hydrodynamics, and propose a new EoS that is simple and yet approximates very closely the EoS of ...

Fast Rotating Neutron Stars: Oscillations and Instabilities
Frontiers in Astronomy and Space Sciences, 2021 In this review article, we present the main results from our most recent research concerning the oscillations of fast rotating neutron stars. We derive a set of time evolution equations for the investigation of non-axisymmetric oscillations of rapidly ...
