Intertwining Topological Order and Broken Symmetry in a Theory of Fluctuating Spin-Density Waves. Physical Review Letters 119: 227002.0031-90071079-7114http://nrs.harvard.edu/urn-3:HUL.InstRepos:41343848The pseudogap metal phase of the hole-doped cuprate superconductors has two seemingly unrelated characteristics: a gap in the electronic spectrum in the "anti-nodal" region of the square lattice Brillouin zone, and discrete broken symmetries. We present a SU(2) gauge theory of quantum fluctuations of magnetically ordered states which appear in a classical theory of square lattice antiferromagnets, in a spin density wave mean field theory of the square lattice Hubbard model, and in a CP1 theory of spinons. This theory leads to metals with an antinodal gap, and topological order which intertwines with precisely the observed broken symmetries.en-USJournal Article2019-09-1110.1103/physrevlett.119.227002
