Electrically tunable Berry curvature and strong light-matter coupling in liquid crystal microcavities with 2D perovskite
Open accessAbstract
The field of spinoptronics is underpinned by good control over photonic spin-orbit coupling in devices that have strong optical nonlinearities. Such devices might hold the key to a new era of optoelectronics where momentum and polarization degrees of freedom of light are interwoven and interfaced with electronics. However, manipulating photons through electrical means is a daunting task given their charge neutrality. In this work, we present electrically tunable microcavity exciton-polariton resonances in a Rashba-Dresselhaus spin-orbit coupling field. We show that different spin-orbit coupling fields and the reduced cavity symmetry lead to tunable formation of the Berry curvature, the hallmark of quantum geometrical effects. For this, we have implemented an architecture of a photonic structure with a two-dimensional perovskite layer incorporated into a microcavity filled with nematic liquid crystal. Our work interfaces spinoptronic devices with electronics by combining electrical control over both the strong light-matter coupling conditions and artificial gauge fields.

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 [28]
The Results (‘Strong light-matter coupling’; page unavailable) identify the studied material as polycrystalline 2D PEPI, not single-crystalline CsPbBr3. The Discussion (page unavailable) describes electrically tunable Berry curvature at room temperature, not long-range propagation or spontaneous coherence of polariton fluids. (LLM, conf=0.84)

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.
