  1. 75. Reducing the pressure of neutron-star cores via IBP

    QCD in extreme conditions and dense nuclear matter
    talk (30min)

    There has been quite some activity in finding methods to evaluate cold+dense vacuum integrals that emerge in perturbative treatments of dense (but deconfined) quark matter, conjectured to play a role in neutron star cores and hence potentially relevant to the gravitational-wave physics of colliding compact stars.

    The purpose of this rather technical talk is to report on progress about...

    QCD in extreme conditions and dense nuclear matter
    talk (30min)

    The equation of state of deconfined strongly interacting matter at high densities remains an open question, with effects from quark pairing in the preferred color-flavor-locked (CFL) ground state possibly playing an important role. Recent studies suggest that at least large pairing gaps in the CFL phase are incompatible with current astrophysical observations of neutron stars. At the same...

  3. 39. Nuclear Chiral Density Wave in Neutron Stars?

    QCD in extreme conditions and dense nuclear matter
    talk (15min)

    Anisotropic phases are hypothesised to play a role in the small temperature and large chemical potential regime of the QCD phase diagram, making their existence in the core of neutron stars a concrete possibility. I will present the study of such a phase, the chiral density wave (CDW), defined as an anistropic chiral condensate. The nuclear CDW is firstly studied within a nucleon-meson model,...

    QCD in extreme conditions and dense nuclear matter
    talk (15min)

    We investigate the possibility of a crystalline phase of dense nuclear matter as a constituent of neutron star cores. Performing a stability analysis of the most stable homogeneous ground state, we first show that symmetric nuclear matter is unlikely to manifest instabilities, however, its phase diagram is extremely likely to be almost completely embedded in a moat-regime, where the...

  5. 11. Intersection of Domain Wall and Vortex in QCD Phases under a Magnetic Field

    QCD in extreme conditions and dense nuclear matter
    talk (15min)

    We study the low-energy QCD phase diagram under a magnetic field and at finite density. Both baryon chemical potential and isospin chemical potential are taken into account. The former is responsible for a domain wall configuration of the neutral pion, dubbed the chiral soliton lattice (CSL), originating from the chiral anomaly. The latter induces the charged pion condensate that can...
