Shear Viscosity in a CFL Quark Star
We compute the shear viscosity in the color-flavor locked (CFL) phase of dense quark matter at low temperature T . Then the contributions of mesons, quarks and gluons to the transport coefficients are Boltzmann suppressed. CFL quark matter displays superfluid properties, and transport phenomena in such cold regime are dominated by phonon-phonon scattering. We study phonons within thermal field ...
متن کاملShear viscosity of degenerate electron matter
We calculate the partial electron shear viscosity ηee limited by electron–electron collisions in a strongly degenerate electron gas taking into account the Landau damping of transverse plasmons. The Landau damping strongly suppresses ηee in the domain of ultrarelativistic degenerate electrons and modifies its temperature behavior. The efficiency of the electron shear viscosity in the cores of w...
متن کاملShear viscosity of neutron matter from realistic nucleon-nucleon interactions.
The calculation of transport properties of Fermi liquids, based on the formalism developed by Abrikosov and Khalatnikov, requires the knowledge of the probability of collisions between quasiparticles in the vicinity of the Fermi surface. We have carried out a study of the shear viscosity of pure neutron matter, whose value plays a pivotal role in determining the stability of rotating neutron st...
متن کاملBulk viscosity in nuclear and quark matter: a short review
The history and recent progresses in the study of bulk viscosity in nuclear and quark matter are reviewed. The constraints from baryon number conservation and electric neutrality in quark matter on particle densities and fluid velocity divergences are discussed. The time scale for damping of the vibration and of the gravitational radiation driven instability in neutron stars is crucial to the s...
متن کاملBulk viscosity in 2SC and CFL quark matter
The bulk viscosities of two color-superconducting phases, the color-flavor locked (CFL) phase and the 2SC phase, are computed and compared to the result for unpaired quark matter. In the case of the CFL phase, processes involving kaons and the superfluid mode give the largest contribution to the bulk viscosity since all fermionic modes are gapped. In the case of the 2SC phase, ungapped fermioni...
