The pseudogap state of high-temperature superconductors is a profound mystery. It contains tantalizing evidence of a number of broken symmetry states, not necessarily conventional charge- and spin-density waves. Here we explore a class of more exotic density wave states characterized by topological properties observed in recently discovered topological insulators. We suggest that these rich topological density wave states deserve closer attention not only in high-temperature superconductors but in other correlated electron states as well.
