Abstract

Under a unified theory we investigate the formation of various types of vector solitons in two-species Bose-Einstein condensates with arbitrary scattering lengths. We then show that by tuning the interaction parameter via Feshbach resonance, transformation between different types of vector solitons is possible. Our results open up alternate ways in the quantum control of multispecies Bose-Einstein condensates.
