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…

Bloch and Bethe ansatze for the Harper model: A butterfly with a boundary
Qiao-Ru Xu, Emilio Cobanera, Gerardo Ortiz
Based on a recent generalization of Bloch's theorem, we present a Bloch ansatz for the Harper model with an arbitrary rational magnetic flux in various geometries, and solve the as…
