“…It was theoretically suggested that two of the three quarks inside a proton may form color Cooper pair. The composite boson of color Cooper pair and the rest quark maybe can exist as boson-fermion mixture [15]. The theoretical possibility of a transition from Fermi gas of three quarks to boson-fermion mixture of quarks was revealed by T-matrix method [16].…”

Boson-fermion mixture exist in nature as quark-gluon plasma and 3 He-4 He mixture. We proposed a convective boson-fermion pairing theory, that can be implemented by ultracold atoms in optical superlattice transformation between different configurations. This transformation may induce the collision and division between boson and fermion, which defines a theoretical convective pairing state. The paring Hamiltonian is Hermitian but it always generate a complex energy spectrum. Each finite gap state can be classified by a topological winding number. The stable pairing state only exists for certain discrete momentum vector zones. An unstable linear dispersion connects two neighboring stable pairing states. The boson-fermion gap function controls the momentum gap space between two neighboring pairing state. The critical temperature of transition from a gapped to gapless phase shows a maximal value at negative fermion chemical potential. The density of state for the pairing excitation diverges at low energy, thus most pairing states are observable at low energy.
