论文摘要
我们研究了单个两级原子与单光子探针脉冲之间在纳米纤维的指导模式下之间的相互作用。我们检查了手性相互作用的情况，该原子在纳米纤维的子午平面上具有偶极子旋转，并且探针脉冲沿纤维横向平面中原子位置的径向方向进行准确偏振。我们表明，原子激发概率，光子传输通量和光子传输概率取决于沿纤维轴的探针脉冲的传播方向。相反，反射通量和反射概率不取决于探针脉冲的传播方向。我们发现原子激发概率的不对称参数不会随时间变化，也不取决于探针脉冲形状。
We study the interaction between a single two-level atom and a single-photon probe pulse in a guided mode of a nanofiber. We examine the situation of chiral interaction, where the atom has a dipole rotating in the meridional plane of the nanofiber, and the probe pulse is quasilinearly polarized along the radial direction of the atom position in the fiber transverse plane. We show that the atomic excitation probability, the photon transmission flux, and the photon transmission probability depend on the propagation direction of the probe pulse along the fiber axis. In contrast, the reflection flux and the reflection probability do not depend on the propagation direction of the probe pulse. We find that the asymmetry parameter for the atomic excitation probability does not vary in time and does not depend on the probe pulse shape.
