Observation of fermion-mediated interactions between bosonic atoms
In high-energy and condensed-matter physics, particle exchange has an essential role in the understanding of long-range interactions and correlations. For example, the exchange of massive bosons leads to the Y...

Testing universality of Efimov physics across broad and narrow Feshbach resonances
The emergence of Efimov states in ultracold atomic systems is expected to have a universal behaviour, but a new experimental study defies this expectation, reporting a clear deviation around a narrow Feshbach ...
