Mapping between Morita equivalent string-net states with a constant depth quantum circuit
Laurens Lootens, Bram Vancraeynest-De Cuiper, Norbert Schuch +1
We construct a constant depth quantum circuit that maps between Morita equivalent string-net models. Due to its constant depth and unitarity, the circuit cannot alter the topologic…
Dualities in one-dimensional quantum lattice models: symmetric Hamiltonians and matrix product operator intertwiners
Laurens Lootens, Clement Delcamp, Gerardo Ortiz +1
We present a systematic recipe for generating and classifying duality transformations in one-dimensional quantum lattice systems. Our construction emphasizes the role of global sym…
A critical lattice model for a Haagerup conformal field theory
Robijn Vanhove, Laurens Lootens, Maarten Van Damme +4
We use the formalism of strange correlators to construct a critical classical lattice model in two dimensions with the \emph{Haagerup fusion category} as input data…
Variational methods for characterizing matrix product operator symmetries
Anna Francuz, Laurens Lootens, Frank Verstraete +1
We present a method of extracting information about topological order from the ground state of a strongly correlated two-dimensional system represented by an infinite projected ent…
Topological aspects of the critical three-state Potts model
Robijn Vanhove, Laurens Lootens, Hong-Hao Tu +1
We explore the topological defects of the critical three-state Potts spin system on the torus, Klein bottle and cylinder. A complete characterization is obtained by breaking down t…
