Abstract: We analyze the phase diagram of a three-flavor Nambu-Jona-Lasinio model at finite temperature T and chemical potentials µu, µd, µs. 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.
