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… 
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{ Pitaevskii
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.
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.
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 $SU(2)$ quantum

Mesoscopics of half-quantum vortex pair deconfinement in a trapped spin-one condensate
Motivated by a recent experiment in an antiferromagnetic spin-1 Bose-Einstein condensate of ${}^{23} \textrm{Na}$ atoms, we study the energetical stability of a singly quantum vortex injected into
Exact nonlinear dynamics of Spinor BECs applied to nematic quenches
In this thesis we study the nonlinear dynamics of spin-1 and spin-2 BoseEinstein condensates, with particular application to antiferromagnetic systems exhibiting nematic (beyond magnetic) order.
Resonance phenomena in a two-layer two-vortex shear flow.
The paper deals with a dynamical system governing the motion of two point vortices embedded in the bottom layer of a two-layer rotating flow experiencing linear deformation and their influence on
Vortices and magnetic bags in Abelian models with extended scalar sectors and some of their applications
A detailed study of vortices is presented in Ginzburg-Landau (or Abelian Higgs) models with two complex scalars (order parameters) assuming a general U(1)×U(1) symmetric potential. Particular
Phase ordering dynamics in a ferromagnetic spin-1 Bose-Einstein condensate
Spinor Bose-Einstein condensates exhibit both superfluid and magnetic order, and accommodate phases with rich symmetry properties and topological defects. Transitions between these phases can be
