Explicit Symplectic Integrators for Massive Point Vortex Dynamics in Binary Mixture of Bose--Einstein Condensates
Tomoki Ohsawa
We construct explicit integrators of arbitrary even orders of accuracy for massive point vortex dynamics in binary mixture of Bose--Einstein condensates proposed by Richaud et al.…

Small-Mass Asymptotics of Massive Point Vortex Dynamics in Bose--Einstein Condensates I: Averaging and Normal Forms
Tomoki Ohsawa, Andrea Richaud, Roy Goodman
We perform an asymptotic analysis of massive point-vortex dynamics in Bose--Einstein condensates in the small-mass limit . We define two distinguished manifolds…
