Many-body chemical reactions in a quantum degenerate gas
Chemical reactions in the quantum degenerate regime are described by the mixing of matter-wave fields. In many-body reactions involving bosonic reactants and products, such as coupled atomic and molecular Bose...

Pattern formation in a driven Bose–Einstein condensate
Pattern formation is ubiquitous in nature at all scales, from morphogenesis and cloud formation to galaxy filamentation. How patterns emerge in a homogeneous system is a fundamental question across interdiscip...

Engaged in gauge theory
Two independent cold-atom experiments have demonstrated the building blocks for the quantum simulation of dynamical gauge fields — an advance that holds promise for our understanding of computationally intract...

Quantum simulation of Unruh radiation
The exploration of quantum phenomena in a curved spacetime is an emerging interdisciplinary area at the interface between general relativity1–4, thermodynamics4–6 and quantum information7,8. One famous prediction...

Coherent inflationary dynamics for Bose–Einstein condensates crossing a quantum critical point
Quantum phase transitions, transitions between many-body ground states, are of extensive interest in research ranging from condensed-matter physics to cosmology 1–4 . Key featu...

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 ...

Bound to be universal?
Three papers published in Nature Physics in 2009 revealed the intriguing three- and four-body bound states arising from the predictions by Vitaly Efimov nearly half a century ago. But some of these findings conti...

Direct observation of effective ferromagnetic domains of cold atoms in a shaken optical lattice
Ultracold atoms in optical lattices are used to study various phenomena in condensed-matter physics, such as magnetism. A lattice-shaking technique can induce a strong effective spin-interaction, leading to th...
