Isometrization of Tensor Network States via Gauge Propagation
We introduce a gauge-propagation approach for approximately converting generic tensor-network states into an isometric tensor-network state form with a prescribed orthogonality center.
The method identifies propagation-compatible local decompositions as useful building blocks for approximate isometrization and as potential initializers or preconditioners for variational isoTNS algorithms.
