We review the status of cooling techniques aimed at achieving the deepest quantum
degeneracy for atomic Fermi gases. We first discuss some physics motivations, providing a …

The notion of quasi-particles is essential for understanding the behaviour of complex many-
body systems. A prototypical example of a quasi-particle is a polaron, formed by an impurity …

Ultracold molecules are ideal platforms for many important applications, ranging from
quantum simulation,,,–and quantum information processing, to precision tests of …

We demonstrate site-resolved imaging of individual fermionic Li 6 atoms in a single layer of
a 3D optical lattice. To preserve the density distribution during fluorescence imaging, we …

We employ radio-frequency spectroscopy to investigate a polarized spin mixture of ultracold
Li 6 atoms close to a broad Feshbach scattering resonance. Focusing on the regime of …

Complex molecular structure demands customized solutions to laser cooling by extending
its general set of principles and practices. Compared with other laser-cooled molecules …

We report on nondestructive imaging of optically trapped calcium monofluoride molecules
using in situ Λ-enhanced gray molasses cooling. 200 times more fluorescence is obtained …

Second sound attenuation, a distinctive dissipative hydrodynamic phenomenon in a
superfluid, is crucial for understanding superfluidity and elucidating critical phenomena …

We demonstrate fluorescence microscopy of individual fermionic potassium atoms in a 527-
nm-period optical lattice. Using electromagnetically induced transparency cooling on the …

The Josephson effect is a macroscopic quantum phenomenon that reveals the broken
symmetry associated with any superfluid state. Here we report on the observation of the …
