Quantum many-body analysis of spin-2 bosons with two-body inelastic decay
Takeshi Takahashi, Hiroki Saito
Bose-Einstein condensates of atoms with a hyperfine spin of 2 are open quantum systems, where the atoms are lost through two-body inelastic collisions. In this d…

Spontaneous creation of skyrmions in a two-component Bose-Einstein condensate
Rabeea Kiran, Hiroki Saito
We investigate the stability of a vortex ring in a miscible two-component Bose-Einstein condensate confined in a harmonic potential, where the vortex cores in the two components ar…

Quantum droplets with magnetic vortices in spinor dipolar Bose-Einstein condensates
Shaoxiong Li, Hiroki Saito
Motivated by the recent experimental realization of a Bose-Einstein condensate (BEC) of europium atoms, we investigate the self-bound droplet state of a europium BEC with spin degr…
