  • The scrambling of quantum information in a many-body system leads to the emergence of statistical mechanics and chaotic behaviour. Here the authors establish quantitative relationships between experimentally-measureable correlators, the Rényi entropy and Lyapunov exponents in the Dicke model.

  • The ability to produce polar molecules in an optical lattice is used to prepare a system where occupied lattice sites contain a Bose-Fermi doublon. Here, the authors apply this approach to optimize the polar molecule creation process and to study complex out-of-equilibrium Bose-Fermi-Hubbard dynamics.

  • An array-based high-throughput approach termed Escherichia coli synthetic genetic array, or eSGA, now allows comprehensive genetic interaction screens in bacteria. The method makes use of bacterial conjugation and robotic technology to generate double mutants on a genome-wide scale. In this issue, another paper presents GIANT-coli, a very similar approach.

  • Isolated many-body quantum systems do not thermalize with an external environment but in most cases the internal dynamics leads to the emergence of an effective thermal equilibrium for local degrees of freedom. Here the authors study this behaviour with a realization of a long-range spin model.

  • The dynamics of quantum information and entanglement is closely linked to the physics of thermalization. A quantum simulator comprised of superconducting qubits has measured the spread of quantum information in a many-body system.

  • The dynamics of quantum information is opening new perspectives on the behaviour of complex many-body systems. This Perspective covers progress made with atomic gases and trapped ions for accessing the dynamics of quantum correlations, entanglement and information scrambling in a broad parameter regime.

  • Clock spectroscopy of ultracold strontium atoms in a three-dimensional optical lattice is used to observe the onset of multi-body interactions that result from the underlying pairwise interactions between atoms.
