Lett. 88, 057003 (2002) DOI: 10.1103/PhysRevLett.88.057003 | | Subject: | Superconductivity; Strongly Correlated Electrons | cond-mat.supr-con cond-mat.str-el | | Affiliation: | ITP Wuerzburg), M. Troyer (ETH Zuerich), and S.C. Zhang (ITP Stanford | | Abstract: | We present numerical studies of a quantum ``projected’’ SO(5) model which aims at a unifying description of antiferromagnetism and superconductivity in the high-T$_c$ cuprates, while properly taking into account the Mott insulating gap. Our numerical results, obtained by the Quantum Monte Carlo technique of Stochastic Series Expansion, show that this model can give a realistic description of the global phase diagram of the high-$T_c$ superconductors and accounts for many of their physical properties. Moreover, we address the question of dynamic restoring of the SO(5) symmetry at the critical point. | | Source: | arXiv, cond-mat/0106473 | | Services: | Forum | Review | PDF | Favorites | |
