Josephson Dynamics of 2D Bose-Einstein Condensates in Dual-Core Trap: Homogeneous, Droplet-Droplet, and Vortex-Vortex Regimes
Josephson oscillation frequencies and bifurcation structures are derived for homogeneous, quantum droplet, and vortex states in 2D BEC mixtures in dual-core traps using extended Gross-Pitaevskii equations, with numerical validation for droplets and identification of Andreev-Bashkin drag and vortex (
