WebThe surface wave modes on right-handed helically grooved metal wire waveguide and left-handed one were studied and compared. It was found that for the helically grooved waveguide, the normal degenerate HE1 SSPP (spoof surface plasmon polaritons) mode decompose into two opposite circularly polarized modes, i.e., HE − 1 and HE + 1 SSPP … WebJan 25, 2024 · We demonstrate room temperature chiral coupling of valley excitons in a transition metal dichalcogenide monolayer with spin-momentum locked surface plasmons. At the onset of the strong coupling regime, we measure spin-selective excitation of directional flows of polaritons. Operating under such conditions, our platform yields …

WebMoreover, the chiral surface conductivity, determined by the interlayer quantum coupling, determines the existence of chiral plasmons and leads to a unique phase relationship (i.e., ±π/2 phase difference) between their transverse-electric (TE) and transverse-magnetic (TM) wave components. Importantly, such a unique phase relationship for ... WebThe salient features of these chiral plasmons are shown through their dependence on optical pumping intensity and electron fillings, in conjunction with distinct resonance splitting and Faraday rotation coinciding with the spectral window of maximal Berry flux. Moreover, we also identify a slow plasmonic mode around 0.4 electronvolts, which ... WebNov 29, 2024 · These chiral surface plasmons possess momentum-location lock and strong confinement of electromagnetic (EM) fields. The anomalous Hall conductivity brings about abundant anisotropic plasmon dispersions, from linear to parabolic or even hyperbolic bands. In addition, a semiclassical picture of electron motion is proposed to show the … cypher语言学习
