Giant optical spin-orbit interactions in ferroelectric van der Waals waveguides

Ding Xu, Saeed Rahmanian Koshkaki, Vicente Galicia +14

Optical spin-orbit interactions (SOI) link photonic spin to momentum, offering a route toward on-chip polarization control and beam steering. Nevertheless, achieving sufficient opt…

Exciton Delocalization Suppresses Polariton Scattering

Yongseok Hong, Ding Xu, Milan Delor

Exciton-polaritons (EPs) are part-light part-matter quasiparticles that combine large exciton-mediated nonlinearities with long-range coherence, ideal for energy harvesting and non…

Observation of Coherent Ferron Emission and Propagation

Jeongheon Choe, Taketo Handa, Chun-Ying Huang +16

Excitation of ordered quantum phases gives rise to collective modes and quasiparticles, as exemplified by spin waves and magnons emerging from magnetic order. Extending this paradi…
