TL;DR: In this paper, a review mainly concentrates on the properties of pion degrees of freedom in nuclear and neutron matter, and deals with various phenomena in atomic nuclei and neutron stars for which pion mode softening plays an important part.

TL;DR: In this article, the effects of strong interactions on the weak interaction rates were investigated using both potential and effective field-theoretical models of matter, and the relative importance of charged and neutral currents for different astrophysical situations, and also examined the influence of strangeness-bearing hyperons.
Abstract: We study the charged and neutral current weak interaction rates relevant for the determination of neutrino opacities in dense matter found in supernovae and neutron stars. We establish an efficient formalism for calculating differential cross sections and mean free paths for interacting, asymmetric nuclear matter at arbitrary degeneracy. The formalism is valid for both charged and neutral current reactions. Strong interaction corrections are incorporated through the in-medium single particle energies at the relevant density and temperature. The effects of strong interactions on the weak interaction rates are investigated using both potential and effective field-theoretical models of matter. We investigate the relative importance of charged and neutral currents for different astrophysical situations, and also examine the influence of strangeness-bearing hyperons. Our findings show that the mean free paths are significantly altered by the effects of strong interactions and the multicomponent nature of dense matter. The opacities are then discussed in the context of the evolution of the core of a protoneutron star.

TL;DR: In this paper, a brief history of neutron stars and supernovae recent developments are discussed, and the nuclear to quark matter phase transition and its mixed phases with intriguing structures are treated.
Abstract: After a brief history of neutron stars and supernovae recent developments are discussed. Based on modern nucleon-nucleon potentials more reliable equations of state for dense nuclear matter have been constructed. Furthermore, phase transitions such as pion, kaon and hyperon condensation, superfluidity and quark matter can occur in cores of neutron stars. Specifically, the nuclear to quark matter phase transition and its mixed phases with intriguing structures is treated. Rotating neutron stars with and without phase transitions are discussed and compared to observed masses, radii and glitches. The observations of possible heavy $\sim 2M_\odot$ neutron stars in X-ray binaries and QPO's require relatively stiff equation of states and restricts strong phase transitions to occur at very high nuclear densities only.

TL;DR: An effective hadronic lagrangian consistent with the symmetries of quantum chromodynamics and intended for applications to finite-density systems is constructed in this article, where the degrees of freedom are (valence) nucleons, pions and the low-lying non-Goldstone bosons, which account for the intermediate-range nucleon-nucleon interactions.

TL;DR: The thermodynamically consistent procedure to introduce the excluded volume effect into the equation of state of nuclear matter has been presented in this article, in the framework of a mean-field model for hadrons with eigenvolume.
Abstract: We present the thermodynamically consistent procedure to introduce the excluded volume effect into the equation of state of nuclear matter. Implications are discussed in the framework of a mean-field model for hadrons with eigenvolume.
