Calculations within QCD-inspired models as well within QCD in the large-N_c limit show that dense quark matter features inhomogeneous phases. The order parameter for chiral symmetry breaking varies periodically, in the form of a chiral density wave ("chiral spiral") or in the functional form of a Jacobi elliptic function. In this talk, I will demonstrate that this phenomenon also occurs...

With the measurements of two-solar-mass neutron stars the question of how to reconcile the existence of large masses with the possibility of more exotic compact objects like hyper stars and hybrid stars has gained major importance. In order to address this point theoretical approaches to model stars containing quarks as well as nucleons and hyperons are discussed, also considering the general...

I model hybrid compact stars making use of a self-consistent equations of state. In this approach, the degrees of freedom change from hadrons to quarks in a self-consistent way. This means that the particles appear, in principle, in arbitrary proportions with the interactions leading to the correct behavior for low, respectively high, densities and temperatures. Chiral symmetry restoration and...

The Field Correlator Method provides an approximation of the full Quantum Chromodynamics Equation of State (EoS) for quark matter, which is parametrized in terms of the gluon condensate and the large distance quark-antiquark potential. This EoS can be confronted with the hadronic EoS to analyze the phase transition from nuclear to quark matter, thus providing a simple framework to...

We study the quark-hadron phase transition with the finite size effects for neutron star matter. Generally, non-uniform structures appear in the phase transition of multi-component system. Namely, we call them as the pasta structures. In this study, the properties of the mixed phase are clarified by considering the finite size effects. We find that, if the surface tension is strong, the EOS...
