Simple Hamiltonians for Matrix Product State models
Norbert Schuch, Andras Molnar, David Perez-Garcia
Matrix Product States (MPS) and Tensor Networks provide a general framework for the construction of solvable models. The best-known example is the Affleck-Kennedy-Lieb-Tasaki (AKLT…

Frustration free gapless Hamiltonians for Matrix Product States
Carlos Fernández-González, Norbert Schuch, Michael M. Wolf +2
For every Matrix Product State (MPS) one can always construct a so-called parent Hamiltonian. This is a local, frustration free, Hamiltonian which has the MPS as ground state and i…
