Acoustic Black Hole in a Stationary Hydrodynamic Flow of Microcavity Polaritons
Open accessAbstract
We report an experimental study of superfluid hydrodynamic effects in a one-dimensional polariton fluid flowing along a laterally patterned semiconductor microcavity and hitting a micron-sized engineered defect. At high excitation power, superfluid propagation effects are observed in the polariton dynamics; in particular, a sharp acoustic horizon is formed at the defect position, separating regions of sub- and supersonic flow. Our experimental findings are quantitatively reproduced by theoretical calculations based on a generalized Gross-Pitaevskii equation. Promising perspectives to observe Hawking radiation via photon correlation measurements are illustrated.

Alternatively, the downstream region can be left unpumped so that the photon fluid ballistically expands into this region; this configuration was experimentally realized.
“Alternatively, the downstream region can be left unpumped so that the photon fluid is able to ballistically expand into this region.This latter configuration was experimentally realized in [97].”

Numerical studies based on the Wigner formalism have shown that a clear signature of Hawking radiation is present in the correlation function of density fluctuations on opposite sides of the horizon.

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.
