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…

Non-relativistic conformal invariance in mesoscopic two-dimensional Fermi gases
Two-dimensional Fermi gases with universal short-range interactions are known to exhibit a quantum anomaly, where a classical scale and conformal invariance is broken by quantum effects at strong

High-temperature superfluidity in an ultracold Fermi gas
This thesis presents experiments in which a strongly interacting gas of fermions was brought into the superfluid regime. The strong interactions are induced by a Feshbach scattering resonance that
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.
Bound states, Cooper pairing, and Bose condensation in two dimensions.
For a dilute gas of fermions interacting via an arbitrary pair potential in d = 2 dimensions, we show that the many-body ground state is unstable to s-wave pairing at T = 0 if and only if a two-body
Superconductivity in a two-dimensional Fermi gas: Evolution from Cooper pairing to Bose condensation.
It is found that a two-body bound state in vacuum is a necessary and sufficient condition for an s-wave pairing instability and the existence of such a boundState in a higher-angular-momentum (lg0) channel is not a necessary conditions for an l- wave pairing instability.

A system of a few attractively interacting fermionic $^6$Li atoms in one-dimensional harmonic confinement is investigated. Non-trivial inter-particle correlations induced by interactions in a
Mott-insulator transition in a two-dimensional atomic Bose gas.
The 2D Bose-Hubbard model is realized by loading a Bose/Einstein condensate into an optical lattice, and the resulting Mott insulator is studied to show a marked dependence on the lattice depth.
A quantum gas microscope for detecting single atoms in a Hubbard-regime optical lattice
A quantum gas ‘microscope’ that bridges the two approaches to creating highly controllable quantum information systems, realizing a system in which atoms of a macroscopic ensemble are detected individually and a complete set of degrees of freedom for each of them is determined through preparation and measurement.
Review: Superconductivity in ultrasmall metallic grains
We review recent experimental and theoretical work on superconductivity in ultrasmall metallic grains, i.e. grains sufficiently small that the conduction electron energy spectrum becomes discrete.
