Sculpting Bose-Einstein condensate to generate calibrated matter waves.

      Аннотация: The ability to trap and manipulate atoms at lower dimensions with laser light has had a tremendous development in generating coherent matter waves in the realm of the emerging field of atomtronics. The present book provides a detailed theoretical investigation of different quasi-one-dimensional traps in view of how to sculpt both static and dynamic properties of confined Bose-Einstein condensates (BECs). Apart from the introductory part, this book is divided into three parts, which gradually follow on from one to another. We examined that the generation of gray/dark pair-solitons bi-trains represents a generic phenomenon stemming from collisions of the moderately/fully fragmented BEC. It is astonishing to find that the special shape of the generated solitons in the harmonically trapped BEC can be sculptured by imposing a specific geometry. All our findings show that in special circumstances a BEC can be recognized as an atom laser which represents one of the key ingredients for experiments in quantum atom optics, much like the laser is central to the field of a quantum optics.
