Oscillating ring ferrodark solitons with breathing nematic core in a homogeneous spinor superfluid
Xiaoquan Yu
We study the dynamics of ring ferrodark solitons (FDSs) in a homogeneous quasi-two-dimensional (2D) ferromagnetic spin-1 Bose-Einstein condensate (BEC). In contrast to the usual ex…

Motion of ferrodark solitons in trapped superfluids: spin corrections and emergent oscillators
Jiangnan Biguo, Xiaoquan Yu
We propose a framework for topological soliton dynamics in trapped spinor superfluids, decomposing the force acting on the soliton by the surrounding fluid into the buoyancy force…
