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 …

The relaxation of isolated quantum many-body systems is a major unsolved problem
connecting statistical and quantum physics. Studying such relaxation processes remains a …

Interactions between quasiparticles are of fundamental importance and ultimately determine
the macroscopic properties of quantum matter. A famous example is the phenomenon of …

The correlation of the tidal polarizabilities Λ 1-Λ 2 for GW170817 is predicted by combining
dense-matter equations of state (EOSs) that satisfy nuclear physics constraints with the chirp …

Ultracold quantum gases offer a unique setting for quantum simulation of interacting many-
body systems. The high degree of controllability, the novel detection possibilities and the …

We have observed the Bose-Einstein condensation of an atomic gas in the (quasi) uniform
three-dimensional potential of an optical box trap. Condensation is seen in the bimodal …

Fermi gases, collections of fermions such as neutrons and electrons, are found throughout
nature, from solids to neutron stars. Interacting Fermi gases can form a superfluid or, for …

Ultracold atomic gases provide a fantastic platform to implement quantum simulators and
investigate a variety of models initially introduced in condensed matter physics or other …

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 …

Recent experimental and theoretical progress has elucidated the tunable crossover, in
ultracold Fermi gases, from BCS-type superconductors to BEC-type superfluids. The BCS …
