Higher Symmetries in Condensed Matter Physics
R. S. Markiewicz, M. T. Vaughn
Abstract
We discuss some applications of higher symmetry groups to condensed matter systems. We give special attention to the groups SO(n) (n = 4, 5, 6, 8) in the two-dimensional Hubbard model and its generalizations, which model the high Tc cuprate superconductors.
