Speed of sound in dense strong-interaction matter

  title={Speed of sound in dense strong-interaction matter},
  author={Jens Braun and Andreas Geissel and Benedikt Schallmo},
We study the speed of sound in strong-interaction matter in density regimes which are expected to be governed by the presence of a color-superconducting gap. At (very) high densities, our analysis indicates that the speed of sound approaches its asymptotic value associated with the non-interacting quark gas from below, in agreement with first-principles studies which do not take the presence of a color-superconducting gap into account. Towards lower densities, however, the presence of a gap…

The Condensed matter physics of QCD

Important progress in understanding the behavior of hadronic matter at high density has been achieved recently, by adapting the techniques of condensed matter theory. At asymptotic densities, the

Introduction to superfluidity -- Field-theoretical approach and applications

In this pedagogical introduction, I discuss theoretical aspects of superfluidity and superconductivity, mostly using a field-theoretical formalism. While the emphasis is on general concepts and
