Pairing is the fundamental requirement for fermionic superfluidity and superconductivity [1]. To understand the mechanism behind pair formation is an ongoing challenge in the study of many strongly correlated fermionic systems [2]. Here, we directly observe Cooper pairs in a mesoscopic two-dimensional Fermi gas. We apply an imaging scheme that enables us to extract the full in-situ momentum distribution of a strongly interacting Fermi gas with single particle and spin resolution [3]. Our…

High-temperature pairing in a strongly interacting two-dimensional Fermi gas

Radio-frequency spectroscopy shows that strongly interacting fermions start pairing high above the critical temperature, which implies that pairing in this regime is driven by many-body correlations, rather than two-body physics.

Free fermion antibunching in a degenerate atomic Fermi gas released from an optical lattice

The direct observation of antibunching of neutral fermionic atoms is reported by analysing the atomic shot noise in a set of standard absorption images of a gas of fermionics 40K atoms released from an optical lattice and finding reduced correlations for distances related to the original spacing of the trapped atoms.
