| Abstract: | By using the Nambu-Gorkov transformation, the relativistic BCS-BEC crossover thermodynamics in the Fermi-Bose system is discussed, and the exited energy spectrum nearing the critical point is also found. The energy gap equation, in the case of and , is also derived. The results show that there is not a strict critical point in the system, and the zero mass quasiparticles may condense in the critical temperature. |
