Query: Interaction of half-quantized vortices in two-component Bose-Einstein
  condensates   We study the asymptotic interaction between two half-quantized vortices in
two-component Bose-Einstein condensates. When two vortices in different
components are placed at distance 2R, the leading order of the force between
them is found to be (log R/\xi-1/2)/R^3, in contrast to 1/R between vortices
placed in the same component. We derive it analytically using the Abrikosov
ansatz and the profile functions of the vortices, confirmed numerically with
the Gross-Pitaevskii model. We also find that the short-range cutoff of the
inter-vortex potential linearly depends on the healing length.
