Regular and chaotic trajectories can coexist in classical systems, but identifying an equivalent in quantum many-body dynamics is difficult. A feedback protocol on a superconducting processor now reveals and stabilizes such mixed dynamics.

- Weakly interacting spinons and tightly bound triplons in the frustrated quantum spin-Peierls chainNature Physics, Published online: 16 September 2026; doi:10.1038/s41567-026-03447-5 A combination of one-dimensional magnetic frustration and three-dimensional lattice distortions causes the quantum magnet CuGeO3 to form a dimerized state. Now the authors demonstrate how this interplay affects fractionalized quasiparticles of CuGeO3.
- Mechanisms of spatial pattern transition in motile bacterial collectivesNature Physics, Published online: 15 September 2026; doi:10.1038/s41567-026-03416-y Myxococcus xanthus is a bacterial predator that can transition between swarming and rippling behaviours. It is now shown that this transition occurs owing to a combination of local cellular alignment and cell reversal.
- An algorithm to generate two-dimensional critical lattice models using competing anyon condensationNature Physics, Published online: 14 September 2026; doi:10.1038/s41567-026-03438-6 Conformal field theories have a central role in statistical and high-energy theoretical physics. An algorithm to systematically generate critical lattice models described by different conformal field theories has now been identified.
- Generation of a high-intensity, superthermal muonium beam for gravity and laser spectroscopy experimentsNature Physics, Published online: 14 September 2026; doi:10.1038/s41567-026-03433-x A high-intensity, superthermal beam is generated by extracting muonium from a thin layer of superfluid helium. This beam can be used for tests of gravity and laser spectroscopy.
- Electrification mechanisms in sliding liquid and frozen dropsNature Physics, Published online: 14 September 2026; doi:10.1038/s41567-026-03449-3 When sliding along an insulating surface, liquid drops become charged. Experiments with self-ionizing and non-polar liquids on different substrates suggest the competition of at least two underlying mechanisms.
