Self-Maintaining Defect/Energetic Droplets from Two Interacting Bose-Einstein Condensates.

- Abstract
We consider two interacting Bose-Einstein condensates with different kinds of the potential energy of inter- action of the condensates: (a) the standard potential, (b) the potential has a positive three-body and a negative two-body scattering terms, and (c) the potential has a positive four-body and a negative three-body scattering terms for the first Bose-Einstein condensate and a positive three-body and a negative two-body scattering terms for the second Bose-Einstein condensate. It is shown that in these cases there exist stationary regular spherically symmetric solutions. Physically such solution is either a defect or an energetic droplet created by the conden- sates. The defect is a cavity filled with one Bose-Einstein condensate on the background of another Bose-Einstein condensate. The droplet is an object with zero energy density at the infinity. For (a) and (b) cases the obtained objects are supported by a constant external trapping potential and for (c) case the droplet is a self-maintaining object without any external potential. The possibility of construction of an elementary logic qubit device on the basis of this droplet is discussed.
