Vector azimuthons in two-component Bose-Einstein condensates

Lashkin, Volodymyr M; Ostrovskaya, Elena; Desyatnikov, Anton S; Kivshar, Yuri

Description

We introduce matter-wave vector azimuthons, i.e., spatially localized vortex states with azimuthal modulations of density, in multicomponent Bose-Einstein condensates. These localized states generalize spatially modulated vortex solitons introduced earlier in nonlinear optics and Bose-Einstein condensates. We find, numerically, nonrotating and rotating two-component azimuthons in a Bose-Einstein condensate with a negative scattering length confined by a quasi-two-dimensional parabolic trap.
