  • Quantum gases are useful toy models for the study of quantum magnetism. Exquisite control of a spinor gas of fermionic atoms in an optical lattice has now been demonstrated, opening up the exploration of quantum magnetism with high spins.

  • The connection between the topological properties of the ground state and non-equilibrium dynamics remains obscure. Here, Tarnowski et al. define and measure a linking number between static and dynamical vortices, which directly corresponds to the ground-state Chern number.

  • By subjecting a Chern insulator to a circular drive, its geometrical and topological properties would be accessible from the spectroscopic response. This prediction is now confirmed in a Floquet topological system realized by ultracold fermionic atoms.
