在基于二维t-J模型的重整化平均场理论下，研究了d波超导、反铁磁性和交错磁通态中的准粒子性质。特别是，我们重点讨论了桥本等人在自然物理中所讨论的布里渊区反节点区周围的反常准粒子色散关系。6414(2010)。当我们考虑SF态时，我们得到了与他们的观测定性一致的结果。目前的分析表明，SF序可能是与DSC共存的对称破缺赝隙态的一个可能候选者。
We study the quasiparticle properties in the d-wave superconductivity, antiferromagnetism, and the staggered flux state within a renormalized mean-field theory based on the two-dimensional t-J model. In particular, we focus on the anomalous quasiparticle dispersion relations around the antinodal region of the Brillouin zone argued in Hashimoto et al., Nature Phys. 6, 414 (2010). We obtain the qualitatively consistent results with their observations when we take account of the SF state. The present analysis shows that the SF order can be a possible candidate of symmetry-breaking pseudogap states coexisting with the dSC.
