Pion Propagation near the QCD Chiral Phase Transition
D. T. Son, M. A. Stephanov
We point out that, in analogy with spin waves in antiferromagnets, all parameters describing the real-time propagation of soft pions at temperatures below the QCD chiral phase tran…

Kaon Condensation and Goldstone's Theorem
T. Schaefer, D. T. Son, M. A. Stephanov +2
We consider QCD at a nonzero chemical potential for strangeness. At a critical value of the chemical potential equal to the kaon mass, kaon condensation occurs through a continuous…

Asymptotic deconfinement in high-density QCD
D. H. Rischke, D. T. Son, M. A. Stephanov
We discuss QCD with two light flavors at large baryon chemical potential mu. Color superconductivity leads to partial breaking of the color SU(3) group. We show that the infrared p…
