Efficient description of many-body systems with Matrix Product Density Operators
Jiri Guth Jarkovsky, Andras Molnar, Norbert Schuch +1
Matrix Product States form the basis of powerful simulation methods for ground state problems in one dimension. Their power stems from the fact that they faithfully approximate sta…

Inaccessible entanglement in symmetry protected topological phases
Caroline de Groot, David T. Stephen, Andras Molnar +1
We study the entanglement structure of symmetry-protected topological (SPT) phases from an operational point of view by considering entanglement distillation in the presence of sym…

Matrix Product States: Entanglement, symmetries, and state transformations
David Sauerwein, Andras Molnar, J. Ignacio Cirac +1
We analyze entanglement in the family of translationally-invariant matrix product states (MPS). We give a criterion to determine when two states can be transformed into each other…
