On two-dimensional tensor network group symmetries
José Garre-Rubio, András Molnár
We introduce two-dimensional tensor network representations of finite groups carrying a 4-cocycle index. We characterize the associated gapped (2+1)D phases that emerge when these…

Approximating Gibbs states of local Hamiltonians efficiently with PEPS
András Molnár, Norbert Schuch, Frank Verstraete +1
We analyze the error of approximating Gibbs states of local quantum spin Hamiltonians on lattices with Projected Entangled Pair States (PEPS) as a function of the bond dimension ($…
