摘要：In this contribution, I summarise the studies of the properties of Bose-Einstein condensed systems
composed of up to twelve pions or kaons carried out by the NPLQCD collaboration. These
investigations have provided precise determination the I=2 pp and I=1 KK scattering lengths
and the first determination of three-hadron interactions fromm QCD, finding a repulsive threepion
interaction of size consistent with naive dimensional analysis and a three kaon interaction
consistent with zero. We have also determined the isospin (strangeness) density dependence of
the isospin(strangeness) chemical potential, finding results in surprisingly good agreement with
chiral perturbation theory.
