- An algorithm to generate two-dimensional critical lattice models using competing anyon condensation
- 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.
- An intense superthermal muonium beamNature Physics, Published online: 14 September 2026; doi:10.1038/s41567-026-03435-9 Conventional sources of muonium — a bound state of a positively charged muon and an electron — produce diffuse thermal beams. Now an intense, superthermal muonium beam with a velocity distribution far narrower than existing sources has been achieved.
- Criticality from competitionNature Physics, Published online: 14 September 2026; doi:10.1038/s41567-026-03450-w Conformal field theories describe universal physics at quantum critical points, but it is hard to find microscopic models that realize particular field theories. Studying competing boundary conditions of topological phases provides a systematic way to build such models.
- Microrotors make wavesNature Physics, Published online: 14 September 2026; doi:10.1038/s41567-026-03452-8 Thousands of 3D-printed microscopic rotors spontaneously synchronize their motion when assembled into a lattice. Counterintuitively, small imperfections among individual motors drive the propagation of waves across such artificial active matter.
- Digital quantum simulations of scattering in quantum field theories using W statesNature Physics, Published online: 11 September 2026; doi:10.1038/s41567-026-03436-8 Quantum simulations of field-theory scattering require preparing particles and following their collision dynamics. A digital quantum simulation now reveals the inelastic production of particles in one-dimensional Ising field theory.
- A digital twin should make a risky claimNature Physics, Published online: 11 September 2026; doi:10.1038/s41567-026-03411-3 As the term ‘digital twin’ spreads across science and technology, it risks losing scientific meaning. Such a twin should not denote just a digital replica, but a computational model that can be updated, tested against intervention and shown to fail.
