Abstract
We engineer angular momentum eigenstates of a single atom by using an all-optical approach based on the interference of Laguerre-Gaussian beams. We confirm the imprint of angular momentum by measuring the two-dimensional density distribution and by performing Ramsey spectroscopy in a slightly anisotropic trap, which additionally reveals the sense of rotation. This article provides the experimental details on the quantum state control of angular momentum eigenstates reported in P. Lunt et al., Phys. Rev. Lett. 133, 253401 (2024).

Ultracold Fermions Enter the Fractional Quantum Hall Arena
By controlling the motion and interaction of individual atoms in a cold-atom ensemble, researchers have produced a correlated topological state of matter, called a fractional quantum Hall state.
