- Abstract: The Pauli exclusion principle is a fundamental law underpinning the structure
of matter. Due to their anti-symmetric wave function, no two fermions can
occupy the same quantum state. Here, we report on the direct observation of the
Pauli principle in a continuous system of up to six particles in the ground
state of a two-dimensional harmonic oscillator. To this end, we sample the full
many-body wavefunction by applying a single atom resolved imaging scheme in
momentum space. We find so-called Pauli crystals as a manifestation of higher
order correlations. In contrast to true crystalline phases, these unique
high-order density correlations emerge even without any interactions present.
Our work lays the foundation for future studies of correlations in strongly
interacting systems of many fermions.

These geometric structures, called Pauli crystals, are predicted for a two-dimensional system of free fermions under harmonic confinement.
