Generating function for projected entangled-pair states
Wei-Lin Tu, Laurens Vanderstraeten, Norbert Schuch +3
Diagrammatic summation is a common bottleneck in modern applications of projected entangled-pair states, especially in computing low-energy excitations of a two-dimensional quantum…

Entanglement Spectrum as a diagnostic of chirality of Topological Spin Liquids: Analysis of an PEPS
Mark J. Arildsen, Ji-Yao Chen, Norbert Schuch +1
We address the key question of representation of chiral topological quantum states in (2+1) dimensions (i.e., with non-zero chiral central charge) by Projected Entangled Pair State…
