Quantum mechanical superexchange interactions form the basis of quantum magnetism in
strongly correlated electronic media. We report on the direct measurement of …

Tunnelling of material particles through a classically impenetrable barrier constitutes one of
the hallmark effects of quantum physics. When interactions between the particles compete …

The quantum statistics of atoms is typically observed in the behavior of an ensemble via
macroscopic observables. However, quantum statistics modifies the behavior of even two …

Ultracold atoms trapped by light offer robust quantum coherence and controllability,
providing an attractive system for quantum information processing and for the simulation of …

Interactions lie at the heart of correlated many-body quantum phases,,. Typically, the
interactions between microscopic particles are described as two-body interactions …
