    "abstract": "We construct an equation-of-state for nuclear matter based on the chiral\nLagrangian. The relevant scales are discussed and an effective chiral power\nexpansion scheme, which is constructed to work around the nuclear saturation\ndensity, is presented. A realistic equation-of-state is obtained by adjusting\none free parameter, when the leading and subleading terms in the expansion are\nincluded. The saturation mechanism is due to correlations induced by the\none-pion-exchange interaction. Furthermore, we find a substantial deviation\nfrom the Fermi-gas estimate of the quark condensate in nuclear matter already\nat the saturation density.",
