Probing cold dense nuclear matter.
The protons and neutrons in a nucleus can form strongly correlated nucleon pairs. Scattering experiments, in which a proton is knocked out of the nucleus with high-momentum transfer and high missing momentum, show that in carbon-12 the neutron-proton pairs are nearly 20 times as prevalent as proton-proton pairs and, by inference, neutron-neutron pairs. This difference between the types of pairs...
متن کاملMulti fluidity and Solitary wave stability in cold quark matter: core of dense astrophysical objects
Considering the magneto-hydrodynamic equations in a non-relativistic multi uid framework, we study the behavior of small amplitude perturbations in cold quark matter. Magneto-hydrodynamic equations, along with a suitable equation of state for the cold quark matter, are expanded using the reductive perturbation method. It is shown that in small amplitude approximation, such a medium should be co...
متن کاملAspects of Cold Dense Quark Matter
This thesis is devoted to properties of quark matter at high density and (comparatively) low temperature. In nature matter under these conditions can possibly be found in the interior of (some) neutron stars. Under “normal” conditions quarks are confined in the hadrons. Under the extreme conditions in the core of a neutron star, however, the strong interaction between the quarks becomes weaker ...
متن کاملColor Superconductivity in Cold, Dense Quark Matter
We review what is different and what is similar in a color superconductor as compared to an ordinary BCS superconductor. The parametric dependence of the zero-temperature gap, φ0, on the coupling constant differs in QCD from that in BCS theory. On the other hand, the transition temperature to the superconducting phase, Tc, is related to the zero-temperature gap in the same way in QCD as in BCS ...
متن کاملSpin-one Color Superconductivity in Cold and Dense Quark Matter
In this thesis, several color-superconducting phases where quarks of the same flavor form Cooper pairs are investigated. In these phases, a Cooper pair carries total spin one. A systematic classification of theoretically possible phases, discriminated by the color-spin structure of the order parameter and the respective symmetry breaking pattern, is presented. In the weak-coupling limit, i.e., ...
