บทคัดย่อ: In the field of superconductivity the most interesting area is the studying of the mechanism of the high Tc superconductor (HTS). Understanding of this mechanism, we can raise the critical temperature (Tc). There are many proposals theoretical descriptions for HTS. We focus on the spin density wave (SDW) and charge density wave (CDW), the static wave of spin density and charge density arising from the nesting property of Fermi surface that were observed in the superconductor. The model Hamiltonian of superconductor having SDW and CDW coexistence was studied by Greens function method. The analytic expression of zero-temperature gap of superconductor with the coexistence of the SDW and CDW were derived. By varying the effective potential, the phase diagram of the SDW and CDW was constructed then the band structure and density of states (DOS) of coexistent phase were also studied. © (2014) Trans Tech Publications, Switzerland.
