The Fermi Gas team at Laboratoire Kastler Brossel recently published an article in Physical Review Letter. Atom-based quantum simulators offer a unique platform that enables the imaging of each particle in a many-body system. Until now, however, this capability has been limited to quantum systems in discretized space such as optical lattices and tweezers, where… Read more: Quantum Gas Microscopy of Fermions in the Continuum

The Fermi Gas team at LKB recently published an article in the journal Physical Review Letters. The authors: We report on the imaging of the in situ spatial distribution of deterministically prepared single-atom wave packets as they expand in a plane, finding excellent agreement with the scaling dynamics predicted by the Schrödinger equation. Our measurement provides a direct… Read more: In-situ Imaging of a Single-Atom Wave Packet in Continuous Space
