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…
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…
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…
Bulk viscosity from Urca processes: matter in the neutrino-transparent regime
Mark Alford, Arus Harutyunyan, Armen Sedrakian
We study the bulk viscosity of moderately hot and dense, neutrino-transparent relativistic matter arising from weak-interaction direct Urca processes. This work parallels ou…
Phenomenological Relativistic Second-Order Hydrodynamics for Multiflavor Fluids
Arus Harutyunyan, Armen Sedrakian
In this work, we perform a phenomenological derivation of the first- and second-order relativistic hydrodynamics of dissipative fluids. To set the stage, we start with a review of…
Delta-resonances and hyperons in proto-neutron stars and merger remnants
Armen Sedrakian, Arus Harutyunyan
The equation of state (EoS) and composition of dense and hot -resonance admixed hypernuclear matter is studied under conditions that are characteristic of neutron star binary me…
Equation of state and composition of proto-neutron stars and merger remnants with hyperons
Armen Sedrakian, Arus Harutyunyan
Finite-temperature equation of state (EoS) and the composition of dense nuclear and hypernuclear matter under conditions characteristic of neutron star binary merger remnants and s…
Relativistic second-order dissipative hydrodynamics from Zubarev's non-equilibrium statistical operator
Arus Harutyunyan, Armen Sedrakian, Dirk H. Rischke
We present a new derivation of relativistic second-order dissipative hydrodynamics for quantum systems using Zubarev's non-equilibrium statistical-operator formalism. This is achie…
Bulk Viscous Damping of Density Oscillations in Neutron Star Mergers
Mark Alford, Arus Harutyunyan, Armen Sedrakian
In this paper, we discuss the damping of density oscillations in dense nuclear matter in the temperature range relevant to neutron star mergers. This damping is due to bulk viscosi…
Bulk Viscosity of Hot Quark Plasma from Non-Equilibrium Statistical Operator
Arus Harutyunyan, Armen Sedrakian
We provide a discussion of the bulk viscosity of two-flavor quark plasma, described by the Nambu--Jona-Lasinio model, within the framework of Kubo-Zubarev formalism. This discussio…

We present a new derivation of second-order relativistic dissipative fluid dynamics for quantum systems using Zubarev's formalism for the non-equilibrium statistical operator. In p…
Transport coefficients of two-flavor quark matter from the Kubo formalism
Arus Harutyunyan, Dirk H. Rischke, Armen Sedrakian
The transport coefficients of quark matter at non-zero chemical potential and temperature are computed within the two-flavor Nambu--Jona-Lasinio model. We apply the Kubo formalism…
