Non-abelian quantum double models from iterated gauging
David Blanik, José Garre-Rubio
We reconstruct all (2+1)D quantum double models of finite groups from their boundary symmetries through the repeated application of a gauging procedure, extending the existing cons…

Gauging Quantum Phases: A Matrix Product State Approach
David Blanik, José Garre-Rubio, Norbert Schuch
Utilizing the framework of matrix product states, we investigate gauging as a method for exploring quantum phases of matter. Specifically, we describe how symmetry-protected topolo…

Internal structure of gauge-invariant Projected Entangled Pair States
David Blanik, José Garre-Rubio, András Molnár +1
Projected entangled pair states (PEPS) are very useful in the description of strongly correlated systems, partly because they allow encoding symmetries, either global or local (gau…
