On‐Chip Active Supercoupled Topological Cavity

Advanced Materials, Volume 37, Issue 24, June 19, 2025.
The on‐chip supercoupled cavity device is demonstrated realizing a record cavity excitation distance exceeding three wavelengths, leveraging the valley‐conserved supercoupling mechanism in the valley Hall topological system. This optothermal tunable design enables new degrees of freedom for supercoupled photonic cavities in mux‐demux, lasers, sensors ...

Nuclear Rayleigh and whispering gallery waves excited in heavy ion collisions

Physics Letters B, 1980
Abstract The gross structure oscillations recently observed in heavy-ion elastic or inelastic scattering and fusion cross sections are here analyzed in terms of nuclear surface (creep) wave resonances. Their dispersion curves characterize these waves as being of Rayleigh or of Whispering-Gallery type.
