Constructing topological models by symmetrization: A PEPS study
Carlos Fernandez-Gonzalez, Roger S. K. Mong, Olivier Landon-Cardinal +2
Symmetrization of topologically ordered wavefunctions is a powerful method for constructing new topological models. Here, we study wavefunctions obtained by symmetrizing quantum do…
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…
Gapless Hamiltonians for the toric code using the PEPS formalism
Carlos Fernández-González, Norbert Schuch, Michael M. Wolf +2
We study Hamiltonians which have Kitaev's toric code as a ground state, and show how to construct a Hamiltonian which shares the ground space of the toric code, but which has gaple…
