Rotating vortex dipoles in ferromagnets.
Vortex-antivortex pairs are spontaneously created in magnetic elements. In the case of opposite vortex polarities the pair has a nonzero topological charge, and it behaves as a rotating vortex dipole. We find theoretically and confirm numerically its energy as a function of angular momentum and the associated rotation frequencies. The annihilation process of the pair changes the topological cha...
متن کاملImpulse Variables, Vortex Dipoles and Applications
A Lagrangian numerical method based on impulse variables is analyzed. The relation between impulse vectors and vortex dipoles with a prescribed dipole moment is presented and used to adapt the high-accuracy cutoo functions of vortex methods for use in impulse-based methods. The long-time implementation of the impulse method is shown to contain a source of error whose growth in time renders impu...
متن کاملNonlinear beam steering by fractional vortex dipoles
Propagation of optical beams in nonlinear media NLM has been a subject of continuing interest for more than 4 decades due to the possibility for creation of reconfigurable waveguides through the intensity-dependent refractive index change 1,2 . Such optically induced waveguides can guide weak signal beams and pulses 3,4 , which motivates the investigation of novel techniques for manipulation of...
متن کاملObservation of vortex dipoles in an oblate Bose-Einstein condensate.
We report experimental observations and numerical simulations of the formation, dynamics, and lifetimes of single and multiply charged quantized vortex dipoles in highly oblate dilute-gas Bose-Einstein condensates (BECs). We nucleate pairs of vortices of opposite charge (vortex dipoles) by forcing superfluid flow around a repulsive Gaussian obstacle within the BEC. By controlling the flow veloc...
متن کاملDynamics of vortex dipoles in confined Bose–Einstein condensates
Article history: Received 12 June 2011 Accepted 24 June 2011 Available online 29 June 2011 Communicated by V.M. Agranovich We present a systematic theoretical analysis of the motion of a pair of straight counter-rotating vortex lines within a trapped Bose–Einstein condensate. We introduce the dynamical equations of motion, identify the associated conserved quantities, and illustrate the integra...
