Bayesian Constraints on Bosonic Dark Matter in Neutron Stars within a Covariant Density-Functional Equation-of-State Ensemble
Davood Rafiei Karkevandi, Alexander Ayriyan, Armen Sedrakian
We investigate neutron stars admixed with repulsively self-interacting bosonic dark matter (DM) using current multi-messenger observations. The dark component is modeled as a compl…
Superfluidity and Vortex Dynamics in Neutron Stars
Bennett Link, Armen Sedrakian
Neutron stars contain several forms of quantum condensed matter whose microscopic properties control macroscopic rotational dynamics and magnetic behavior of these fascinating obje…
Thermoelectric coefficients of two-flavor quark matter from the Kubo formalism
Harutyun Gabuzyan, Arus Harutyunyan, Armen Sedrakian
The hot quark matter created in heavy-ion collision experiments can exhibit strong temperature and chemical-potential gradients, which in turn can generate electric fields through…
Bulk Viscosity of Two-Flavor Color Superconducting Quark Matter in Neutron Star Mergers
Mark Alford, Arus Harutyunyan, Armen Sedrakian +1
This work investigates the bulk viscosity of warm, dense, neutrino-transparent, color-superconducting quark matter, where damping of density oscillations in the kHz frequency range…
Bayesian inferences on covariant density functionals from multimessenger astrophysical data: The impacts of likelihood functions of low density matter constraints
Jia-Jie Li, Armen Sedrakian
We systematically investigate how the choice between Gaussian and uniform likelihood functions in Bayesian inference affects the inferred bulk properties of compact stars and nucle…
Generalized relativistic second-order dissipative hydrodynamics: coupling different rank tensors
Arus Harutyunyan, Armen Sedrakian
In this work, we extend the formalism of second-order relativistic dissipative hydrodynamics, developed previously using Zubarev's non-equilibrium statistical operator formalism. B…
Bayesian inferences on covariant density functionals from multimessenger astrophysical data: Nucleonic models
Jia-Jie Li, Yu Tian, Armen Sedrakian
[Background] Bayesian inference frameworks incorporating multi-messenger astrophysical constraints have recently been applied to covariant density functional (CDF) models to constr…
The nuclear symmetry energy and the neutron skin thickness in nuclei
G. F. Burgio, H. C. Das, I. Vidana
We investigate possible correlations between the stiffness of the symmetry energy at saturation density, the so-called parameter, and the neutron skin thickness of Ca…
Bulk viscosity of two-color superconducting quark matter in neutron star mergers
Mark Alford, Arus Harutyunyan, Armen Sedrakian +1
We study the bulk viscosity of moderately hot and dense, neutrino-transparent color superconducting quark matter arising from weak-interaction-driven direct URCA processes. The qua…
