Abstract

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.
