Efficient optimization and conceptual barriers in variational finite Projected Entangled-Pair States
Daniel Alcalde Puente, Erik Lennart Weerda, Konrad Schröder +1
Projected entangled pair states (PEPS) on finite two-dimensional lattices are a natural ansatz for representing ground states of local many-body Hamiltonians, as they inherently sa…
Variationally optimizing infinite projected entangled-pair states at large bond dimensions: A split corner transfer matrix renormalization group approach
Jan Naumann, Erik Lennart Weerda, Jens Eisert +2
Projected entangled-pair states (PEPS) have become a powerful tool for studying quantum many-body systems in the condensed matter and quantum materials context, particularly with a…
An introduction to infinite projected entangled-pair state methods for variational ground state simulations using automatic differentiation
Jan Naumann, Erik Lennart Weerda, Matteo Rizzi +2
Tensor networks capture large classes of ground states of phases of quantum matter faithfully and efficiently. Their manipulation and contraction has remained a challenge over the…
