Abstract
We study the non-equlibrium dynamics of an electronic model of competing bond density wave order and -wave superconductivity. In a time-dependent Hartree-Fock+BCS approximation, the dynamics reduces to the equations of motion of operators realizing the generators of SU(4) at each pair of momenta, , in the Brillouin zone. We compare the results of numerical studies of our model with recent picosecond optical experiments.
