Interface properties in three-component Bose-Einstein condensates

Abstract

Interface properties of a three-component Bose-Einstein condensate, in which component 3 is sandwiched by components 1 and 2 at the interface, are investigated. It is shown that component 3 can serve as a surfactant: the net interfacial tension is reduced by the presence of component 3. We calculate the interfacial tension as a function of the interaction coefficients. The stability of the interface is studied by Bogoliubov analysis. When the interfacial tension has a spatial gradient, interfacial flow is induced, which resembles the Marangoni flow.
