We review the physics of pair-density wave (PDW) superconductors. We begin with a
macroscopic description that emphasizes order induced by PDW states, such as charge …

This report addresses topics and questions of common interest in the fields of ultra-cold
gases and nuclear physics in the context of the BCS–BEC crossover. By this crossover, the …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

Originally, the Hubbard model was derived for describing the behavior of strongly correlated
electrons in solids. However, for over a decade now, variations of it have also routinely been …

Fermi systems in the cross-over regime between weakly coupled Bardeen–Cooper–
Schrieffer (BCS) and strongly coupled Bose–Einstein-condensate (BEC) limits are among …

Ultracold Fermi gases with tunable interactions provide a test bed for exploring the many-
body physics of strongly interacting quantum systems,,,. Over the past decade, experiments …

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 …

Polarons—electronic charge carriers 'dressed'by a local polarization of the background
environment—are among the most fundamental quasiparticles in interacting many-body …

We report on the creation of homogeneous Fermi gases of ultracold atoms in a uniform
potential. In the momentum distribution of a spin-polarized gas, we observe the emergence …

A pair density wave (PDW) is a superconductor whose order parameter is a periodic function
of space, without an accompanying spatially uniform component. Since PDWs are not the …
