在原子局域化的背景下，理论上研究了Λ-系统的行为。除了探测场和驻波驱动场外，还引入了微波场来耦合两个低态，从而使我们的Λ-系统形成一个闭环。因此，相敏原子局域化的预期。事实上，通过适当选择三个场之间的相对相位，已经发现驻波的亚波长域内的原子的检测概率提高了2倍。其他参数的影响也进行了研究。
The behaviour of the Λ-system has been studied theoretically in the context of atom localization. In addition to the probe field and the standing wave driving field, a microwave field is introduced to couple the two lower states, and as a result our Λ-system forms a closed loop. Therefore phase-sensitive atom localization is expected. Indeed by appropriate choice of the relative phase between three fields, an improvement by a factor of 2 has been found in the detection probability of atoms within the sub-wavelength domain of the standing wave. The effect of other parameters is also investigated.
