High-Density Skyrmion Matter and Neutron Stars

  title={High-Density Skyrmion Matter and Neutron Stars},
  author={Prashanth Jaikumar and Manjari Bagchi and Rachid Ouyed},
  journal={The Astrophysical Journal},
We examine neutron star properties based on a model of dense matter composed of B = 1 skyrmions immersed in a mesonic mean field background. The model realizes spontaneous chiral symmetry breaking nonlinearly and incorporates scale breaking of QCD through a dilaton vacuum expectation value that also affects the mean fields. Quartic self-interactions among the vector mesons are introduced on grounds of naturalness in the corresponding effective field theory. Within a plausible range of the… Expand

In this Thesis we present a new method of theoretical studies of magnetic materials. The method is based on the Fourier expansion of the magnetisation and then using this expansion in order toExpand


Skyrmion Stars: Astrophysical Motivations and Implications
We study mass-radius relations for compact stars employing an equation of state (EOS) of dense matter based on a Skyrme fluid. The zero-temperature mean-field model is based on mesonic excitations,Expand
The physics of dense hadronic matter and compact stars
This review describes the properties of hadronic phases of dense matter in compact stars. The theory is developed within the method of real-time Green's functions and is applied to study of baryonicExpand
The Physics of Neutron Stars
Observations that include studies of pulsars in binary systems, thermal emission from isolated neutron stars, glitches from pulsars, and quasi-periodic oscillations from accreting neutron stars provide information about neutron star masses, radii, temperatures, ages, and internal compositions.

The puzzles of RX J1856.5-3754: neutron star or quark star?
Abstract We discuss recent Chandra and XMM-Newton observations of the bright isolated neutron star RX J1856.5–3754 and suggest that the absence of any line features is due to effects of a highExpand
Soft equations of state for neutron-star matter ruled out by EXO 0748 - 676
A determination of the mass and radius of the neutron star EXO 0748 - 676 that appears to rule out all the soft equations of state of neutron-star matter, suggesting that condensates and unconfined quarks do not exist in the centres of neutron stars. Expand
A skyrmion fluid
Abstract A fluid of skyrmions coupled to the dilaton field and the ω meson field is considered. A mean field theory is developed in which the dilaton and the ω field acquire a mean value determinedExpand

Abstract The matter in neutron stars is essentially in its ground state and ranges in density up to and beyond 3 × 10 14 g/cm 3 , the density of nuclear matter. Here we determine the constitution ofExpand
