Normal projected entangled pair states generating the same state
Andras Molnar, José Garre-Rubio, David Pérez-García +2
Tensor networks are generated by a set of small rank tensors and define many-body quantum states in a succinct form. The corresponding map is not one-to-one: different sets of tens…

Projected Entangled Pair States: Fundamental analytical and numerical limitations
G. Scarpa, A. Molnar, Y. Ge +4
Matrix Product States (MPS) and Projected Entangled Pair States (PEPS) are powerful analytical and numerical tools to assess quantum many-body systems in one and higher dimensions,…
