Dynamics of spinor Bose-Einstein condensates close to spin-spatial resonances
The study develops a coupled-channel framework to describe spinor Bose-Einstein condensates near spin-spatial resonances. By using Bogoliubov modes as a basis, the method reveals two types of resonant excitations: those with particle-hole correlations and those without. This framework is more accurate than standard theories for capturing long-time dynamics near these resonances.
