Topological order, emergent gauge fields, and Fermi surface reconstruction

S Sachdev - Reports on Progress in Physics, 2018 - iopscience.iop.org
This review describes how topological order associated with the presence of emergent
gauge fields can reconstruct Fermi surfaces of metals, even in the absence of translational …
