  We study the color-spin interaction energy of a quark, a diquark and a baryon
with their surrounding baryons and/or quark matter. This is accomplished by
classifying all possible flavor and spin states of the resulting multiquark
configuration in both the flavor SU(2) and SU(3) symmetric cases. We find that
while the baryon has the lowest interaction energy when there is only a single
surrounding baryon, the quark has the lowest interaction energy when the
surrounding has more than three baryons or becomes a quark gas. As the short
range nucleon-nucleon interactions are dominated by the color-spin
interactions, our finding suggests that the baryon modes near other baryons are
suppressed due to larger repulsive energy compared to that of a quark and thus
provides a quark model basis for the quarkyoniclike phase in dense matter. At
the same time, when the internal interactions are taken into account, and the
matter density is high so that the color-spin interaction becomes the dominant
interaction, the diquark becomes the lowest energy configuration and will thus
appear in both the dense baryonic and/or quark matter.
