Super-resolution microscopy of single atoms in optical lattices

Andrea Alberti, Carsten Robens, Wolfgang Alt +5 more

We report on image processing techniques and experimental procedures to determine the lattice-site positions of single atoms in an optical lattice with high reliability, even for limited acquisition time or optical resolution. Determining the positions of atoms beyond the diffraction limit relies on parametric deconvolution in close analogy to methods employed in super-resolution microscopy. We develop a deconvolution method that makes effective use of the prior knowledge of the optical transfer function, noise properties, and discreteness of the optical lattice. We show that accurate knowledge of the image formation process enables a dramatic improvement on the localization reliability. This allows us to demonstrate super-resolution of the atoms' position in closely packed ensembles where the separation between particles cannot be directly optically resolved. Furthermore, we demonstrate experimental methods to precisely reconstruct the point spread function with sub-pixel resolution from fluorescence images of single atoms, and we give a mathematical foundation thereof. We also discuss discretized image sampling in pixel detectors and provide a quantitative model of noise sources in electron multiplying CCD cameras. The techniques developed here are not only beneficial to neutral atom experiments, but could also be employed to improve the localization precision of trapped ions for ultra precise force sensing.

Nanosecond super-resolved imaging of a single cold atom by stimulated emission depletion microscopy

Zhong-Hua Qian, Jin‐Ming Cui, Xi-Wang Luo +6 more

As one of the most critical methods for optical super-resolved microscopy, stimulated emission depletion (STED) microscopy has been widely applied in biological and chemical fields, leading to the Nobel prize of 2014 in chemistry. In cold atomic systems, fast and high-resolution microscopy of individual atoms is crucial since it can provide direct information on the dynamics and correlations of the system. Here, we demonstrate nanosecond two-dimensional snapshots of a single trapped ion beyond the optical diffraction limit, by combining the main idea of STED with the quantum state transition control in cold atoms. We achieve a spatial resolution up to 175 nm and a time resolution up to 50 ns simultaneously using a NA=0.1 objective in the experiment, which is improved over ten times compared to direct fluorescence imaging. To show the potential of this method, we applied it to record the motion of the trapped ion and observe one cycle of the secular motion of the ion with a displacement detection sensitivity of 10 nm. Our method provides a powerful tool for probing particles' positions, momenta and correlations, as well as their dynamics in cold atomic systems.

Superresolution Microscopy of Cold Atoms in an Optical Lattice

Mickey McDonald, Jonathan Trisnadi, Kai-Xuan Yao +1 more

A new superresolution imaging technique reveals the behavior of cold atoms in an optical lattice with a spatial resolution of 32 nm and moir\'e patterns that are hugely magnified images of the microscopic atomic density distribution itself.
