After decades of improvements in cooling techniques of several atomic species and in
finding methods for the achievement of stable quantum mixtures, the field is now ready for …

Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

Monopoles and vortices are fundamental topological excitations that appear in physical
systems spanning enormous scales of size and energy, from the vastness of the early …

One of the most sought-after objects in topological quantum-matter systems is a vortex
carrying half a quantum of circulation. They were originally predicted to exist in superfluid He …

Microcavity exciton‐polaritons are attractive quantum quasi‐particles resulting from strong
light–matter coupling in a quantum‐well‐cavity structure. They have become one of the most …

We demonstrate that a quasi-two-dimensional spin-1 condensate quenched to a
ferromagnetic phase undergoes universal coarsening in its late time dynamics. The quench …

The equivalence between particles under rotation and charged particles in a magnetic field
relates phenomena as diverse as spinning atomic nuclei, weather patterns, and the …

We study the propagation of sound waves in a binary superfluid gas with two symmetric
components. The binary superfluid is constituted using a Bose-Einstein condensate of Na 23 …

We report the observation of spin domain walls bounded by half-quantum vortices (HQVs) in
a spin-1 Bose-Einstein condensate with antiferromagnetic interactions. A spinor condensate …

Symmetries of the physical world have guided formulation of fundamental laws, including
relativistic quantum field theory and understanding of possible states of matter. Topological …
