Cold, dense quark matter
This thesis discusses the properties of cold quark matter as exists in the core of massive neutron stars, with baryon densities several times of nuclear saturation density, n_0 ≈ 0.16 fm^-3, at zero temperature. Specifically, we study effective quark models, the symmetry pattern of different quark …

The crystallography of three flavor quark matter
The nature of cold three-flavor quark matter at the large (but not asymptotic) densities relevant to neutron star phenomenology is not resolved. The gapless CFL phase, which was previously believed to have the lowest free energy, was recently shown to be unstable in the sense that some phase must …

Color superconducting phase of cold dense quark matter
… investigate color superconducting phases of cold quark matter at densities relevant for the interiors of compact stars. At these densities, electrically neutral and weak-equilibrated quark matter can have unequal numbers of up, down, and strange quarks. The QCD interaction favors Cooper pairs that …

A search for strange quark matter in the -0.75T field setting of E864
… as a high sensitivity search for strange quark matter produced in heavy ion collisions at the AGS accelerator at Brookhaven National Laboratory. In this thesis, we analyze data taken at the -0.75T field setting of the experiment, which is optimal for finding negatively charged strangelet …

Gapless color superconductivity
… phase, a possible new phase of dense and cold quark matter. At high enough densities, quarks interact with each other and form pairs similarly to electrons in superconductors. This phenomenon in the case of quark matter is called Color Superconductivity. Color superconducting matter must be …

From quarks to cold atoms: the phases of strongly-interacting systems
… we investigate the phase structure of dense quark matter, the structure and stability of neutron and quark stars, and the phases of ultracold fermions in the presence of an artificial spin-orbit coupling. While spanning an extraordinary twenty orders of magnitude in energy scales, these …

Superdense objects in general relativity : modeling neutron stars with free quark cores
… stars made of a color-flavor locked (CFL) quark matter center and a nuclear fluid exterior. CFL quark matter is a theoretical state of matter which may exist at the center of highly dense neutron stars. To verify its existence, we need to make falsifiable predictions about the differences …

Probing the phases of cold ultra-dense matter using neutron star physics
Matter at very high densities and low temperatures is predicted to be in a “color superconducting” phase. At high enough densities, quark matter is in the Color-Flavor-Locked: CFL) phase, but the possible phases of matter at intermediate densities are unknown. Since the density at the core of a …

Two key questions about color superconductivity
… What are the effects of the large strange quark mass, and what are the observable consequences of color superconductivity? Motivated by the first question, we study crystalline color superconductivity. We adapt the Nambu-Gor'kov formalism to study this phase, and go on to examine …

Equation of state of rotating neutron stars
… has been constructed, which is based on the Quark-Meson Coupling model (QMC model), using the method developed by Hartle for slowly rotating compact stars. To determine tidal Love number method suggested by ’Hinderer’ is adopted. In this thesis, neutron star properties are calculated at the …

Ground state and thermal dynamics of strong interaction
… of strong interaction. This is done in terms of quarks which interact by a local chiral four-fermion NJL-interaction at a scale of order 1 GeV. To address the non-perturbative dynamics, we derive renormalization group flow equations in next to leading order in the derivative expansion that go …

Thomas Fermi model for mesons and new noise subtraction techniques in lattice QCD.
Lattice QCD calculations of quark loop operators are extremely time-consuming to evaluate. To calculate these diagrams we use stochastic noise methods, which employ a randomly generated set of noise vectors to project out physical signals. This is done with linear equation solvers like GMRES-DR …

A complete calculation of Shear Viscosity in Strongly Interacting matter
… the unexplored field of the high temperature T Quark-Gluon Plasma, with new discoveries that seem to enforce the hypothesis that such an exotic state of Strongly Interacting matter can indeed exist, making it an established fact. Things in the finite baryon density opposite regime are much …

Study of the properties of dilute Fermi gases in the strongly interacting regime
… alkali gases and color superconductivity of the quark matter. Unlike the two component fluids, zero potential range limit cannot be reached without causing collapse of the system. We also study the scaling behavior of the three-body system. We calculate the threshold of the three-body bound state …
