Improved contraction of finite projected entangled pair states
Markus Scheb
We present an improved version of the algorithm contracting and optimizing finite projected entangled pair states (fPEPS) in conjunction with projected entangled pair operators (PE…

Finite Projected Entangled Pair States for the Hubbard model
Markus Scheb, Reinhard M. Noack
We adapt and optimize the projected-pair-entangled-state (PEPS) algorithm on finite lattices (fPEPS) for two-dimensional Hubbard models and apply the algorithm to the Hubbard model…
