A new model and its physics
Abstract
The high temperature superconductivity in cuprate materials1 has puzzled scientists over twenty years. We must find a new way to understand superconductivity. It is found the spin-charge correlation may dominate the superconductivity2, and we base our judgment upon the features of various superconductors. Thus we presented the idea that superconductivity could be described by correlations. To develop this idea into a quantitative theory, the first work is to give a model and show that various superconductivities can be included in this model. Moreover, superconductivity can originate from the spin-singlet pairing3 or from the spin-triplet pairing4. The spin-singlet pairing favors to appear at the border of antiferromagnetism5, while the spin-triplet pairing favors to appear at the border of ferromagnetism6. The coexistence between superconductivity and magnetism is also possible7,8. Therefore, the second work is to reveal the relation between superconductivity and magnetism.
