Abstract

Abstract Spin-orbit coupling plays an important role in the spin Hall effect and topological insulators. Bose-Einstein condensates with spin-orbit coupling show remarkable quantum phase transition. In this work we control an exciton polariton condensate – a macroscopically coherent state of hybrid light and matter excitations – by virtue of the Rashba-Dresselhaus (RD) spin-orbit coupling. This is achieved in a liquid-crystal filled microcavity where CsPbBr 3 perovskite microplates act as the gain material at room temperature. Specifically, we realize an artificial gauge field acting on the CsPbBr 3 exciton polariton condensate, splitting the condensate fractions with opposite spins in both momentum and real space. Besides the ground states, higher-order discrete polariton modes can also be split by the RD effect. Our work paves the way to manipulate exciton polariton condensates with a synthetic gauge field based on the RD spin-orbit coupling at room temperature.

  • Single-crystalline CsPbBr3 can sustain stable polariton fluids with long-range propagation and spontaneous coherence at room temperature.

    “The single-crystalline CsPbBr 3 , as demonstrated in our earlier studies, can sustain stable polariton fluids with long-range propagation and spontaneous coherence at room temperature [27-30].”

    From Trembling Motion of Exciton Polaritons Close to the Rashba-Dresselhaus Regime (2024) · cites this paper as [27]

    The Abstract reports a CsPbBr3 exciton-polariton condensate at room temperature, and the Results report interference fringes above threshold as evidence of macroscopic coherence. The Results describe the condensate as localized to about 5 μm; our copy does not establish long-range propagation or stability of a polariton fluid, or specify that the microplate is single-crystalline.

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.
