It is currently understood that there are four fundamental forces in nature: gravitational,
electromagnetic, weak and strong forces. The strong force governs the interactions between …

The interaction between nucleons determines the properties of nuclei. It remains a
challenge to understand the relation between the lower-resolution description of nuclei …

We consider the resonant Fermi gas, that is, two-component fermions in three dimensions
interacting by a short-range potential of large scattering length. We introduce a quantity, the …
