关于玻色-爱因斯坦凝聚体的光散射理论

On a theory of light scattering from a Bose-Einstein condensate

Victoria Ezhova, Leonid Gerasimov, Dmitriy Kupriyanov

摘要:

本文研究了存在于玻色-爱因斯坦凝聚体(BEC)相中的宏观原子样品的弹性光散射的量子理论。在第二种量子化形式之后,我们引入了一组对$T$ -矩阵和散射振幅有贡献的极化子传播子的耦合和闭合图方程。我们的方法允许遵循重要的密度校正的准能量结构所造成的静态相互作用和辐射损失与非相干散射的情况下,近共振激发。

英文摘要:

We consider a quantum theory of elastic light scattering from macroscopic atomic sample existing in the Bose-Einstein condensate (BEC) phase. Following to the second quantized formalism we introduce a set of coupled and closed diagram equations for the polariton propagator contributing to the $T$ -matrix and scattering amplitude. Our approach allows to follow important density correction to the quasi-energy structure caused by static interaction and radiation losses associated with incoherent scattering in the case of near resonance excitation.
