Interface of Two-component Bose-Einstein Condensates in Double-parabola Approximation
Main Article Content
Abstract
In this work we proposed a simple method to determine the coordinate of interface of two-component Bose-Einstein condensates (BECs) in double parabola approximation (DPA). Based on this idea, the static properties of BECs have been investigated totally in DPA
Keywords:
Bose-Einstein condensates, Interface, Double parabola approximation.
