Pion and kaon condensation in a 3-flavor NJL model

Abstract

We analyze the phase diagram of a three-flavor Nambu-Jona-Lasinio model at finite temperature $T$ and chemical potentials ${\mu }_u,{\mu }_d,{\mu }_s$. We study the competition of pion and kaon condensation and we propose a physical situation in which kaon condensation could be led only by light quark finite densities.
