Vortex dynamics in coupled BEC rings is governed by circulating acoustic excitations; frequency and damping are predicted by a hydrodynamic model matching BdG analysis and GPE simulations, with resonant barrier modulation enabling controlled transfer even for density-separated condensates.
In a mesoscopic ring of SU(N) fermions with a localized barrier, current and density profiles arise from the balance between single-particle processes and a high-stiffness spin-correlated state tied to N-fold flux fractionalization.
