标题： Coherent deflection of atomic samples and positional mesoscopic superpositions

摘要： 我们提出一种基于超辐射和超吸收相互作用的协议，以实现由于原子向腔场传递动量而导致的原子样品的相干偏转。 这种动量传递的相干性导致原子样品整体偏转，这是由原子的超辐射脉冲的集体性质及其被腔场的超吸收所引起的。 然后该协议用于构建位置上的宏观原子叠加态。 显示英文摘要

摘要： We present a protocol based on the interplay between superradiance and superabsorption to achieve the coherent deflection of an atomic sample due to the momentum transfer from the atoms to a cavity field. The coherent character of this momentum transfer, causing the atomic sample to deflect as a whole, follows from the collective nature of the atomic superradiant pulse and its superabsorption by the cavity field. The protocol is then used for the construction of positional mesoscopic atomic superpositions.
