We will develop a new class of atomic sensors for the high precision measurements in applied and fundamental physics. We will master the new methods for separating a split atomic sample far apart while maintaining the quantum coherence, to detect the spatial variations of exotic quantum forces. We will learn how to tame the harmful decoherence by either controlling the strength of the two-body interactions or using novel sources of ultra-cold atoms. We will develop the theoretical and the experimental methods to implement a chaos-enhanced atom-light coupled sensor, an avant-garde approach to the ultra-precise metrology.
The accomplishment of the set goals opens new possibilities for a wide range of applications, such as gravimetry and the surface force measurements with the perspective of the future large-scale industrial implementations.
