A review is given of various theoretical approaches for the equation of state (EoS) of dense
matter, relevant for the description of core-collapse supernovae, compact stars, and compact …

In recent years our understanding of neutron stars has advanced remarkably, thanks to
research converging from many directions. The importance of understanding neutron star …

Abstract We review the Nambu-Jona-Lasinio (NJL) approach to the dynamical breaking of
chiral symmetry in Quantum Chromodynamics (QCD). After a general overview of the …

We identify an observable imprint of a first-order hadron-quark phase transition at
supranuclear densities on the gravitational-wave (GW) emission of neutron-star mergers …

The authors review the theory and phenomenology of instantons in quantum
chromodynamics (QCD). After a general overview, they provide a pedagogical introduction …

Investigations of deconfined quark matter within NJL-type models are reviewed, focusing on
the regime of low temperatures and “moderate” densities, which is not accessible by …

The current status of theoretical studies on the quantum chromodynamics (QCD) phase
diagram at finite temperature and baryon chemical potential is reviewed with special …

Several approaches to QCD with two massless quarks at finite temperature T and baryon
chemical potential μ suggest the existence of a tricritical point on the boundary of the phase …

We discuss how the simultaneous crossovers of deconfinement and chiral restoration can
be realized. We propose a dynamical mechanism assuming that the effective potential gives …

We investigate three-color QCD thermodynamics at finite quark chemical potential. Lattice
QCD results are compared with a generalized Nambu Jona-Lasinio model in which quarks …
