Cold, dense quark matter
… Specifically, we study effective quark models, the symmetry pattern of different quark matter phases, the collective modes associated with spontaneous chiral symmetry breaking, a possible realization of quark-hadron continuity in the color-flavor locked (CFL) quark superfluid, and the …

Fermionic superfluids : from cold atoms to high density QCD : gapless (breached pair) superfluidity and kaon condensation
… completely self-consistent approximation to the NJL model of high-density QCD and use these results to demonstrate a microscopic realization of kaon condensation. We describe how to match the mean-field approximation to the low-energy chiral effective theory of pseudo-Goldstone bosons, and we …

Nonperturbative aspects of kaon structure
… of the kaon using the Nambu-Jona-Lasinio (NJL) model with the proper-time regularisation scheme to simulate the effect of quark confinement. The separate contributions of each flavour to the elastic form factor are calculated with and without the effect of dressing at the quark-photon …

Looking Beyond the Standard Model from the Lattice
… of three specific BSM (beyond the standard model) theories. The first model (in chapter 3) describes the spontaneous symmetry breaking pattern in a two dimensional, eight supercharge supersymmetric Yang-Mills theory. We discuss the mechanism responsible for the said symmetry breaking and …

Ground state and thermal dynamics of strong interaction
… 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 beyond the leading renormalizable couplings and include …

Gapless color superconductivity
… dense quark matter using a Nambu-Jona- Lasinio (NJL) model, that might be a good guide for understanding the QCD phase diagram.

STRONGLY INTERACTING MATTER:ANALYSIS OF QCD PHASE DIAGRAM BY THERMODYNAMIC GEOMETRY
… I applied this method to LATTICE QCD and HRG models, to Nambu-Jona Lasinio model, and to study the effect of fluctuations in Quark-Meson model, and it is the first application of thermodynamic geometry to field theory at finite temperature and density. The phase transition has been studied …

From quarks to cold atoms: the phases of strongly-interacting systems
… of QCD, the Polyakov–Nambu–Jona-Lasinio (PNJL) model. We construct the QCD phase diagram for two and three quark flavors, giving special attention to the effect of the intermediate strange quark mass on the preferred quark pairing structure at intermediate to high density. In addition, we …
