Locality of temperature and correlations in the presence of non-zero-temperature phase transitions
Senaida Hernández Santana, Andras Molnar, Christian Gogolin +2
While temperature is well understood as an intensive quantity in standard thermodynamics, it is less clear whether the same holds in the presence of strong correlations, especially…
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…
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,…
