Symmetry-protected sign problem and magic in quantum phases of matter

no code implementations26 Oct 2020 Tyler D. Ellison, Kohtaro Kato, Zi-Wen Liu, Timothy H. Hsieh

We introduce the concepts of a symmetry-protected sign problem and symmetry-protected magic to study the complexity of symmetry-protected topological (SPT) phases of matter.
