Description
In this talk I will discuss the properties of the 2SC-phase of dense quark matter. We formulate the quark-meson diquark model as an effective low energy model of QCD. We then calculate the thermodynamic potential to one loop including quark loops. The phase diagram in the $\mu_B-T$ plane is mapped out. We focus on the speed of sound $c_s$ at $T=0$. $c_s$ has a distinct peak of $c_s\approx0.4$ at around $\mu\approx0.4$ GeV and approaches the conformal limit from above. This general behavior seems to be a generic feature of these types of effective models as the same behavior is found at finite isospin chemical potential.
