We study the interaction and dynamics of two half-quantized vortices in two-component Bose- Einstein condensates. Using the Pade approximation for the vortex core profile, we calculate the intervortex potential, whose asymptotic form for a large distance has been derived by Eto et al. [Phys. Rev. A, 83, 063603 (2011)]. Through numerical simulations of the two-dimensional Gross-Pitaevskii equations, we reveal different kinds of dynamical trajectories of the vortices depending on the combinations… Expand
Phase separation of quantized vortices in two-component miscible Bose-Einstein condensates in a two-dimensional box potential
The dynamics of quantized vortices in two-dimensional two-component miscible Bose-Einstein condensates (BECs) trapped by a box potential has been numerically studied using the Gross{ PitaevskiiExpand
Collisional Dynamics of Half-Quantum Vortices in a Spinor Bose-Einstein Condensate.
TLDR
The relaxation dynamics of turbulent condensates containing many HQVs are investigated, and it is demonstrated that spin wave excitations are generated by the collisional motions of the HQVs. Expand
Interactions and scattering of quantum vortices in a polariton fluid
TLDR
A polariton system is used to experimentally investigate the behavior and scattering of vortices in a two-component superfluid, revealing the role of nonlinearity, as well as of density and phase gradients, in driving their rotational dynamics. Expand
Confinement of half-quantized vortices in coherently coupled Bose-Einstein condensates: Simulating quark confinement in a QCD-like theory
We demonstrate that the confinement of half-quantized vortices (HQVs) in coherently coupled Bose-Einstein condensates (BECs) simulates certain aspects of the confinement in $SU(2)$ quantumExpand
