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- Tc 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- Tc superconductors and accounts for many of their physical properties. Moreover, we address the question of asymptotic restoring of the SO(5) symmetry at the critical point.
