The Standard Model has been successful in describing the elementary particles and their interactions. However, a missing piece is a coherent description of the strong interaction in the confinement domain. This puzzle manifests itself in the non-perturbative properties of the proton: neither its mass, its spin nor its radius are straight-forward to understand from first principles....
The measurement of the Lamb shift in muonic hydrogen and the subsequent emergence of the proton radius puzzle have motivated an experimental campaign devoted to other light muonic atoms, such as muonic deuterium and helium. For these systems, nuclear structure corrections are the largest source of uncertainty and constitute the bottle-neck for exploiting the experimental precision to extract...
We study 3-body loss in bundles of quasi-1D gases using ultracold Cs atoms in 2D optical lattices. We take the atoms out of equilibrium using the quantum Newton’s cradle method, varying the average energy deposited and the strength of confinement in the tubes. Taking advantage of the system’s near integrability, we can infer the center of mass energy of all 3-body inelastic collisions that...
