Local Characterization of Global Tensor Network Eigenstates
feeds.aps.org · By José Garre Rubio, András Molnár, Norbert Schuch & Frank Verstraete ·
The Brief
- The paper studies conditions under which matrix product states (MPSs) or matrix product operators are exact eigenvectors of an extensive local operator such as a Hamiltonian.
- The authors are José Garre Rubio, András Molnár, Norbert Schuch and Frank Verstraete.
- The work is published by the American Physical Society (DOI 10.1103/5m7t-q2f6).
Why it matters
Tensor network states are a standard numerical and analytical tool for quantum many-body systems, so clarifying when they are exact eigenstates of local operators shows which models they can describe exactly.
