摘要：

A trapped, phase separated, two component Bose-Einstein condensate (BEC) can be configured to give a single BEC bubble that floats freely in the surrounding BEC. We point out that this system gives a unique template to carry out mesoscopic quantum studies and to detect weak forces. We demonstrate the detection capabilities by proposing and studying a "quantum level" for fundamental quantum fluctuation studies and for mapping the potential energy landscape near a surface with exquisite accuracy.
