Thermodynamics of condensed matter with strong pressure-energy correlations [PDF]
, 2012 We show that for any liquid or solid with strong correlation between its $NVT$ virial and potential-energy equilibrium fluctuations, the temperature is a product of a function of excess entropy per particle and a function of density, $T=f(s)h(\rho ...

Thermodynamic Properties and Equation of State for Solid and Liquid Aluminum
Metals, 2022 High-temperature equations of state for solid and liquid aluminum were constructed herein using experimental data on thermodynamic properties, thermal expansion, compressibility, bulk modulus and sound velocity measurements, supplemented with phase ...

Hyperons in neutron stars and supernova cores [PDF]
, 2016 The properties of compact stars and their formation processes depend on many physical ingredients. The composition and the thermodynamics of the involved matter is one of them. We will investigate here uniform strongly interacting matter at densities and

Neutron stars in the Witten-Sakai-Sugimoto model
Journal of High Energy Physics, 2023 We utilize the top-down holographic QCD model, the Witten-Sakai-Sugimoto model, in a hybrid setting with the SLy4, soft chiral EFT and stiff chiral EFT equations of state to describe neutron stars with high precision.

Self-Trapping of Bose-Einstein Condensates in an Optical Lattice: the Effect of the System Dimension
, 2007 In the present paper, we investigate the dynamics of a Bose-Einstein condensates (BEC) loaded into an deep optical lattice of 1D, 2D and 3D, both analytically and numerically.

Phase diagram of MgO from density-functional theory and molecular-dynamics simulations [PDF]
, 1999 We use first-principles methods (no empirical parameters) to establish the phase diagram for the B1(NaCl), B2(CsCl), and liquid phases of MgO. We used density-functional theory with the generalized gradient approximation to predict the equation-of-state [

Future Physics Perspectives on the Equation of State from Heavy Ion Collisions to Neutron Stars [PDF]
, 2020 With the computational power and algorithmic improvements available today, the ongoing STAR/RHIC and HADES/GSI experiments, the future FAIR and NICA facilities becoming operational, and the new precise measurements from NICER and LIGO/VIRGO, the high ...

, 2009 We analyze the phases of the Sakai-Sugimoto model at finite temperature and baryon chemical potential. Baryonic matter is represented either by 4-branes in the 8-branes or by strings stretched from the 8-branes to the horizon.

Steady electric currents in magnetized QCD and their use for the equation of state
Journal of High Energy PhysicsIn this paper we study the emergence of steady electric currents in QCD as a response to a non-uniform magnetic background using lattice simulations with 2 + 1 quark flavors at the physical point, as well as leading-order chiral perturbation theory ...

Journal of High Energy Physics, 2023 In this work, we develop a perturbative method to describe the behavior of a chiral condensate around a spherical black hole whose mass is astrophysically realistic. We use the inverse mass as the expansion parameter for our perturbative series.
