Abstract

Manipulation of nonlinear waves in artificial periodic structures leads to spectacular spatial features, such as generation of gap solitons or onset of the Mott insulator phase transition. Cavity exciton-polaritons are strongly interacting quasiparticles offering large possibilities for potential optical technologies. Here we report their condensation in a one-dimensional microcavity with a periodic modulation. The resulting mini-band structure dramatically influences the condensation process. Contrary to non-modulated cavities, where condensates expand, here, we observe spontaneous condensation in localized gap soliton states. Depending on excitation conditions, we access different dynamical regimes: we demonstrate the formation of gap solitons either moving along the ridge or bound to the potential created by the reservoir of uncondensed excitons. We also find Josephson oscillations of gap solitons triggered between the two sides of the reservoir. This system is foreseen as a building block for polaritonic circuits, where propagation and localization are optically controlled and reconfigurable.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • These effectively attractive interactions keep the condensate localized in space with a soliton-like shape and reduce the condensation threshold with respect to condensation into the expanding positive-mass states at the bottom of the band.

    “These keep the condensate localized in space with a soliton-like shape [112,113] and, in this way, reduce the condensation threshold with respect to condensation into the expanding positive-mass states at the bottom of the band.”

    From How to exploit driving and dissipation to stabilize and manipulate quantum many-body states (2025) · cites this paper as [112]

    The Results section (‘Condensation in bound GS states under cw excitation’; page unavailable) reports a localized gap state with a soliton-like profile and says it condenses instead of lower-energy band states because its overlap with the reservoir makes it kinetically favored. It does not report a comparative condensation threshold for expanding positive-mass states, so the claimed threshold reduction is not established by this paper. (LLM, conf=0.85)

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.
