Superconductivity at standard temperature and pressure is far from the extreme conditions where new fundamental laws of physics are expected to arise. Yet it is widely believed that the Landau-Ginzburg-Wilson-Fisher paradigm of broken symmetry and renormalization does not give a satisfactory account of the phenomenon. Almost a decade ago, we used the Bardeen-Cooper-Shrieffer wavefunction to show that superconductors have topological order. Here we report progress using topological order to look for standard temperature and pressure superconductivity.
