9 Mar 1999 | | Subject: | Superconductivity; Strongly Correlated Electrons | cond-mat.supr-con cond-mat.str-el nucl-th | | Affiliation: | University of Tennessee), Lian-Ao Wu (Jilin University), Yang Sun (University of Tennessee), Cheng-Li Wu (Chung-Yuan Christian University | | Abstract: | We present an SU(4) model of high-$T_c$ superconductivity. One dynamical symmetry of this model corresponds to the previously proposed SO(5) model for unification of superconductivity and antiferromagnetism, but there are two additional dynamical symmetries: SO(4), associated with antiferromagnetic order and SU(2), associated with a D-wave pairing condensate. These provide a 3-phase microscopic model of high-$T_c$ superconductivity and permit a clear understanding of the role played by the SO(5) symmetry. | | Source: | arXiv, cond-mat/9903150 | | Services: | Forum | Review | PDF | Favorites | |
