论文摘要
超低量子气体的混合物是弱等效原理的高精度量子测试的核心，其中必须通过物质波透镜技术达到极低的膨胀速率。我们建议通过采用魔术激光波长为光学镜头电势来简化这种具有挑战性的原子源制剂，以确保所有原子物种都遵循相同的轨迹并体验常见的扩张动力学。通过这种方式，与标准方法相比，混合物的相对形状在整个演化过程中得到了保守，同时将所需的镜头脉冲数量切成一半。
Mixtures of ultracold quantum gases are at the heart of high-precision quantum tests of the weak equivalence principle, where extremely low expansion rates have to be reached with matter-wave lensing techniques. We propose to simplify this challenging atom-source preparation by employing magic laser wavelengths for the optical lensing potentials which guarantee that all atomic species follow identical trajectories and experience common expansion dynamics. In this way, the relative shape of the mixture is conserved during the entire evolution while cutting in half the number of required lensing pulses compared to standard approaches.
