In this work, we present electrically tunable microcavity exciton-polariton resonances in a Rashba-Dresselhaus spin-orbit coupling field. 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.

Annihilation of exceptional points from different Dirac valleys in a 2D photonic system
Our results open the field of non-Hermitian valley-physics and illustrate connections between Hermitian topology and non-Hermitian phase transitions Nature Communications 13, 5340 (2022)
Domain-Wall Topology Induced by Spontaneous Symmetry Breaking in Polariton Graphene
Condensation can occur at the Dirac points in staggered polariton graphene and the symmetry breaking occurring during the condensate buildup leads to the formation of valley-polarized domains. D. D.

Love might be a second-order phase transition
D. D. Solnyshkov and G. Malpuech from the Institute Pascal University Clermont Auvergne and CNRS show that love might be an example of second-order phase transition. This hypothesis allows to describe both love at first sight and love from liking or friendship. Phys. Lett. A, 445, 128245 (2022) https://doi.org/10.1016/j.physleta.2022.128245

The optical Stern-Gerlach Deflection and Young’s experiment in the reciprocal space
Scientists for the first time demonstrated Young’s experiment for photons in the reciprocal space. Spin patterns corresponding to the persistent spin helix and the Stern-Gerlach experiment are realized in an optically anisotropic liquid crystal microcavity. By applying electric voltage across the microcavity, the liquid crystal molecules inside could be rotated in such a way that the light passing through the cavity was forced to change its internal state into right- and left-handed circular polarized components.
