Hyperbolic Polaritons: Steering Quantum Fluids with Geometry

November 10, 2025
Researchers steered how two quantum light-matter fluids talk—by simply rotating them on a photonic-crystal waveguide. The hyperbolic dispersion lets coupling morph smoothly from evanescent to ballistic, revealing tunable gaps, interference fringes, and directed flow. It’s a geometric dial for analogue optical computing and next-gen quantum-inspired simulators.
