Riemannian optimization of isometric tensor networks
Markus Hauru, Maarten Van Damme, Jutho Haegeman
Several tensor networks are built of isometric tensors, i.e. tensors satisfying . Prominent examples include matrix product states (MPS) in canonical form…

Tangent-space methods for truncating uniform MPS
Bram Vanhecke, Maarten Van Damme, Jutho Haegeman +2
A central primitive in quantum tensor network simulations is the problem of approximating a matrix product state with one of a lower bond dimension. This problem forms the central…
