基于双原子超-亚辐射态选择性驱动的空间定向关联辐射OA北大核心CSTPCD
Spatially oriented correlated emission based on selective drive of diatomic superradiance states
对于两个二能级原子组成的系统,当受到方向性可调的激光场驱动,同时原子间存在偶极-偶极相互作用和自发辐射相干的条件下,我们研究系统的双光子发射现象.对于全同原子系统,原子在特殊的几何构型下,能够实现将原子系统选择性激发到超辐射态或亚辐射态,详细讨论了关联函数的角分布情况.对于非全同原子系统,由于原子间的失谐,选择性驱动减弱,但是通过失谐的改变,激光方向调节能够对能级间耦合强度产生显著影响.研究发现调整激光的入射角度和原子的失谐,能够改变原子一阶相干…查看全部>>
In recent years,the radiative properties of atomic systems have been a hot topic in the research fields of quantum optics and quantum information.With the continuous development of nanophotonics,quantum antennas have become an important model for studying atomic radiation.In order to investigate these phenomena in depth,we investigate a system composed of two two-level atoms,and study the two-photon emission phenomenon of diatomic system under conditions of …查看全部>>
