Realization of a Laughlin state of two rapidly rotating fermions

Understand

We realize a Laughlin state of two rapidly rotating fermionic atoms in an optical tweezer.

• By utilizing a single atom and spin resolved imaging technique, we sample the Laughlin wavefunction, thereby revealing its distinctive features, including a vortex distribution in the relative motion, correlations in the particles' relative angle, and suppression of the inter-particle interactions.
• Our work lays the foundation for atom-by-atom assembly of fractional quantum Hall states in rotating atomic gases.
