Many systems like stable nuclei and neutron stars however have quarks confined within nucleons. In this paper we construct a Fermi sea of three-quark nucleon clusters and investigate the change of the quark condensate as a function of baryon density. We study the effect of quark clustering on the in-medium quark condensate and compare results with the traditional approach of modeling hadronic matter in terms of a Fermi sea of deconfined quarks.2255-2264engquark matternuclear matterchiral symmetryquark condensateArtigo10.1142/S0217732303012040WOS:000186533900003Acesso restrito
