SU${}_M$(2)$\times$U${}_C$(1) Gauge Symmetry in High $T_c$ Superconductivity

Abstract

The square lattice structure of $Cu{O}_2$ layers and the strongly correlated property of electrons indicate that the high $T_c$ superconductivity in cuprates can be described by a SO${}_M$(5) coherent pairing state in which a SU${}_M$(2)$\times$U${}_C$(1) gauge symmetry is embedded. The spin and charge fluctuations that characterize the low energy magnetic excitations in cuprates are controlled by this intrinsic SU${}_M$(2)$\times$U${}_C$(1) gauge symmetry.
