Entangled phonons in atomic Bose-Einstein condensates
Open accessAbstract
We theoretically propose the measurement of phonon entanglement as a tool to study the quantum dynamics of atomic Bose-Einstein condensates. In particular, we show that nonseparability of the phonon modes offers a unambiguous signature of the quantum origin of the phonon emission by analog Hawking and dynamical Casimir processes. The method is numerically validated by applying a generalized Peres-Horodecki criterion to a truncated Wigner description of the condensate. Viable strategies to implement the proposed scheme in state-of-the-art experiments are discussed.

The resulting stimulated rather than spontaneous nature of the process may wash out the peculiar quantum entanglement features of Hawking radiation predicted for analog models based on atomic condensates.
“While this makes the correlations easier to detect, the resulting stimulated rather than spontaneous nature of the process may wash out the peculiar quantum entanglement features of Hawking radiation predicted in [100] in the context of analog models based on atomic condensates.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
