  • Statistical correlations between particles play a central role in the study of complex quantum systems. A new study introduces microscopic detection of ultracold molecules and demonstrates the measurement of two-particle correlations.

  • Computer simulations have revealed the topological nature of the liquid–liquid phase transition in colloidal water. This finding might lead to an experimental observation of this topological transition with colloids as building blocks.

  • The study of statistical correlations is central to the description of complex quantum objects. Measurements of density correlation functions of ultracold molecules are now possible through the realization of a molecular quantum gas microscope.

  • The isotropy of a spherical droplet’s surface causes uniform distribution of adsorbed molecules. However, wrapping the droplet by a crystalline monolayer induces structural defects, enabling temperature-controllable positioning of adsorbates.

  • The anomalous Hall effect can signify that a material has a spontaneous magnetic order. Now, twisted bilayer graphene shows this effect at half filling, suggesting that the ground state is valley-polarized.

  • Supercooled water undergoes a liquid–liquid phase transition. The authors show that the two phases have distinct hydrogen-bond networks, differing in their degree of entanglement, and thus the transition can be described by the topological changes of the network.

  • Tensor networks are mathematical structures that efficiently compress the data required to describe quantum systems. An algorithm for the optimal simulation of quantum dynamics based on tensor networks has now been implemented on a trapped-ion processor.

  • Attosecond charge migration in a neutral molecule has been observed to decohere within approximately 10 fs. However, this does not mean that the electronic coherence is irreversibly lost, as the charge migration is observed to revive after 40–50 fs. These findings have the potential to enable laser control of photochemical processes.

  • This month, we celebrate the fiftieth anniversary of Philip Anderson’s landmark essay ‘More is Different’.

  • Experiments with chiral magnets may hold the key to a better understanding of fundamental aspects of transformations between different skyrmionic states, necessary for magnetic memory and logic applications to become a reality.

  • Stacking monolayer WS2 on top of bilayer WSe2 creates conditions where electrons and holes can coexist in the structure. Their Coulomb interaction allows them to form bound pairs and hence an excitonic insulator state.

  • Long-lived entanglement is a key resource for quantum metrology with optical clocks. Rydberg-based entangling gates within arrays of neutral atoms enable the generation of clock-transition Bell states with high fidelity and long coherence times.
