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…

Entanglement compression in scale space: from the multiscale entanglement renormalization ansatz to matrix product operators
Karel Van Acoleyen, Andrew Hallam, Matthias Bal +3
The multiscale entanglement renormalization ansatz (MERA) provides a constructive algorithm for realizing wavefunctions that are inherently scale invariant. Unlike conformally inva…

Uhlmann fidelities from tensor networks
Markus Hauru, Guifre Vidal
Given two states and of a quantum many-body system, one may use the overlap or fidelity to quantify how similar they are. To further r…
