摘要:

本文提出了一种确定三维光晶格中单原子位置的方法。原子稀疏地从远离共振的光镊加载到位于高分辨率显微镜物镜附近的立方光晶格的几个垂直平面中。在实验的单一实现中,我们将原子钉在深晶格中,然后获得具有单点分辨率的多个荧光图像。物镜在图像之间平移,使晶格的不同晶格平面聚焦。我们的方法的适用性进行评估,使用模拟的荧光图像,在晶格中的原子填充分数是不同的。这开辟了使用量子气体显微镜从二维到三维扩展量子模拟的可能性。

英文摘要:

We demonstrate a method to determine the position of single atoms in a three-dimensional optical lattice. Atoms are sparsely loaded from a far-off-resonant optical tweezer into a few vertical planes of a cubic optical lattice positioned near a high-resolution microscope objective. In a single realization of the experiment, we pin the atoms in deep lattices and then acquire multiple fluorescence images with single-site resolution. The objective is translated between images, bringing different lattice planes of the lattice into focus. The applicability of our method is assessed using simulated fluorescence images, where the atomic filling fraction in the lattice is varied. This opens up the possibility of extending the domain of quantum simulation using quantum gas microscopes from two to three dimensions.
