We show that ultracold fermions in an artificial magnetic field open up a new window to the physics of the spinful fractional quantum Hall effect. We numerically study the lowest energy states of strongly interacting few-fermion systems in rapidly rotating optical microtraps. We find that skyrmion-like ground states with locally ferromagnetic, long-range spin textures emerge. To realize such states experimentally, rotating microtraps with higher-order angular momentum components may be used to… Expand

Geometric squeezing into the lowest Landau level
TLDR
Squeezing of geometric quantum uncertainty is implemented, resulting in a rotating Bose-Einstein condensate occupying a single Landau gauge wave function, resolving the extent of zero-point cyclotron orbits and demonstrating geometric squeezing of the orbits’ centers 7 decibels below the standard quantum limit.

Observation of Laughlin states made of light
TLDR
Pairs of photons in the Laughlin state are created using a gas of strongly interacting, lowest-Landau-level polaritons as a photon collider and show that these photons avoid each other and exhibit angular momentum correlations, the hallmarks of Laughlin physics. Expand
