Classification of Matrix-Product Unitaries with Symmetries
Zongping Gong, Christoph Sünderhauf, Norbert Schuch +1
We prove that matrix-product unitaries (MPUs) with on-site unitary symmetries are completely classified by the (chiral) index and the cohomology class of the symmetry group , pr…

Projected Entangled Pair States with continuous virtual symmetries
Henrik Dreyer, J. Ignacio Cirac, Norbert Schuch
We study Projected Entangled Pair States (PEPS) with continuous virtual symmetries, i.e., symmetries in the virtual degrees of freedom, through an elementary class of models with S…
