Optical angular momentum and atoms

Sonja Franke‐Arnold

Any coherent interaction of light and atoms needs to conserve energy, linear momentum and angular momentum. What happens to an atom's angular momentum if it encounters light that carries orbital angular momentum (OAM)? This is a particularly intriguing question as the angular momentum of atoms is quantized, incorporating the intrinsic spin angular momentum of the individual electrons as well as the OAM associated with their spatial distribution. In addition, a mechanical angular momentum can arise from the rotation of the entire atom, which for very cold atoms is also quantized. Atoms therefore allow us to probe and access the quantum properties of light's OAM, aiding our fundamental understanding of light-matter interactions, and moreover, allowing us to construct OAM-based applications, including quantum memories, frequency converters for shaped light and OAM-based sensors.This article is part of the themed issue 'Optical orbital angular momentum'.

The atomic quantum ring

Patrik Öhberg

We investigate the dynamics of neutral fermions trapped in a one-dimensional ring. We construct an effective magnetic field in the ring using the adiabatic motion of dark states created by light beams carrying an orbital angular momentum. We illustrate the effect of the orbital angular momentum by looking at the induced mass current and show how the Aharonov–Bohm effect manifests itself in an atomic Fermi gas as a periodic mass current as a function of the optically induced artificial magnetic flux.

Delocalized Correlations in Twin Light Beams with Orbital Angular Momentum

Alberto M. Marino, Vincent Boyer, Raphael C. Pooser +3 more

We generate intensity-difference-squeezed Laguerre-Gauss twin beams of light carrying orbital angular momentum by using four-wave mixing in a hot atomic vapor. The conservation of orbital angular momentum in the four-wave mixing process is studied as well as the spatial distribution of the quantum correlations obtained with different configurations of orbital angular momentum. Intensity-difference squeezing of up to -6.7 dB is demonstrated with beams carrying orbital angular momentum. Delocalized spatial correlations between the twin beams are observed.
