Many-body entanglement

At sufficiently low temperatures, many-particle quantum systems can enter a wide variety of exotic phases that go much beyond the usual gas-liquid-solid paradigm. Only recently has it been discovered that some of these phases are uniquely characterized by long-ranged entanglement.

We are interested in identifying the phases that can be only understood by studying their entanglement content. In sight of experimental studies, we also investigate which entanglement measures can be used to characterize these phases and we design protocols for measuring entanglement in experimental setups (see also the topic Novel measurement tools).
