Abstract: The effective potential analysis indicates that, in a 3D two-flavorGross-Neveu model in vacuum, depending on less or bigger than the criticalvalue 2-3 of $G S-H P$, where $G S$ and $H P$ are respectively the couplingconstants of scalar quark-antiquark channel and pseudoscalar diquark channel,the system will have the ground state with pure diquark condensates or withpure quark-antiquark condensates, but no the one with coexistence of the twoforms of condensates. The similarities and differences in the interplay betweenthe quark-antiquark and the diquark condensates in vacuum in the 2D, 3D and 4Dtwo-flavor four-fermion interaction models are summarized.
