Branching microtubule nucleation plays a major part in cellular processes driving eukaryotic cell division. A combination of microscopy approaches and hydrodynamic theory is used to show how the condensed protein TPX2 on a microtubule reorganizes according to the Rayleigh–Plateau instability.Charge radii of exotic potassium isotopes challenge nuclear theory and the magic character of <i>N</i> = 32
Nature Physics, Published online: 28 January 2021; doi:10.1038/s41567-020-01136-5
The charge radii of potassium isotopes up to 52K are measured, and show no sign of magicity at 32 neutrons as previously suggested in calcium. The observations are interpreted with coupled cluster and density functional theory calculations.Publisher Correction: Enhanced thermal Hall effect in the square-lattice Néel state

Nature Physics, Published online: 25 January 2021; doi:10.1038/s41567-020-01118-7
Among the many reasons a signal may deviate from perfect periodicity, quantum-limited jitter is arguably the most fundamental. A clever experiment has now stripped away technical noise to unveil quantum-limited jitter of ultrafast soliton frequency combs.Quantum diffusion of microcavity solitons
Nature Physics, Published online: 25 January 2021; doi:10.1038/s41567-020-01152-5
Quantum jitter fundamentally limits the performance of microresonator frequency combs. The timing jitter of the solitons that generate the comb spectra is analysed, reaching the quantum limit and establishing fundamental limits for soliton microcombs.Publisher Correction: Resonant phase-matching between a light wave and a free-electron wavefunction

The magnetic properties of intercalated metal dichalcogenides are dramatically affected by small crystal imperfections, potentially providing design principles and materials for spintronic devices.Maximum information states for coherent scattering measurements
Nature Physics, Published online: 21 January 2021; doi:10.1038/s41567-020-01137-4
Wavefront shaping can reduce uncertainties due to measurement noise through disordered media—key to many imaging applications. Optimal precision can be achieved using light fields that are eigenstates of an operator related to the medium’s scattering matrix.Exchange bias due to coupling between coexisting antiferromagnetic and spin-glass orders
Nature Physics, Published online: 21 January 2021; doi:10.1038/s41567-020-01123-w
Coexistence of a spin-glass phase with antiferromagnetism in an intercalated crystal produces a large exchange bias effect. This is due to the interplay of disorder and frustration.Publisher Correction: A charge-density-wave topological semimetal

Nature Physics, Published online: 18 January 2021; doi:10.1038/s41567-020-01149-0
The combination of disorder and strong interactions makes it hard to understand the nature of doped silicon’s insulating phase. State-of-the-art spectroscopy measurements show marginal electronic behaviour reminiscent of what is seen in the cuprates.Decay and recurrence of non-Gaussian correlations in a quantum many-body system
Nature Physics, Published online: 18 January 2021; doi:10.1038/s41567-020-01139-2
Starting from a strongly correlated state, with highly non-Gaussian correlations, a Gaussian state can emerge dynamically over time.
