Robustness of the thermal Hall effect close to half-quantization in α-RuCl<sub>3</sub>

Nature Physics - Thu, 17/02/2022 - 00:00

Nature Physics, Published online: 17 February 2022; doi:10.1038/s41567-021-01501-y

Earlier measurements of quantized heat transport in the spin liquid candidate α-RuCl3 agreed with the predictions of Majorana edge modes. Support for this interpretation now comes from the observations of quantization across a large parameter range.

Clock qubit conducts nuclear ensemble

Good to see you again

Nature Physics - Mon, 14/02/2022 - 00:00

Nature Physics, Published online: 14 February 2022; doi:10.1038/s41567-022-01530-1

As in-person conferences begin to make a return, we look forward to the opportunity to reconnect.

Still too small to be measured

Nature Physics - Mon, 14/02/2022 - 00:00

Nature Physics, Published online: 14 February 2022; doi:10.1038/s41567-021-01495-7

Although the mass of the electron antineutrino is still eluding direct measurement, the KATRIN experiment with its huge spectrometer has pushed the sensitivity below a billionth of the proton mass.

Measure in circles

Nature Physics - Mon, 14/02/2022 - 00:00

Nature Physics, Published online: 14 February 2022; doi:10.1038/s41567-021-01500-z

Entanglement can provide an extra boost in precision, but entangled states are hard to detect. A recent experiment solves this problem by letting the entangling dynamics come full circle — or not, depending on the subtle perturbation to be sensed.

A gelation transition enables the self-organization of bipolar metaphase spindles

Nature Physics - Thu, 10/02/2022 - 00:00

Nature Physics, Published online: 10 February 2022; doi:10.1038/s41567-021-01467-x

The activity of molecular motors drives the self-organization of cytoskeleton structures, leading to large-scale active flows. Now, experiments and simulations show how a gelation process enables such long-range transport in spindles.

Noise phased out

Nature Physics, Published online: 07 February 2022; doi:10.1038/s41567-021-01486-8

Environmental noise can severely hinder the storage and transmission of quantum information. Experiments now reveal that trapped ions are promising candidates for reliable quantum memories.

Error correction of a logical grid state qubit by dissipative pumping

Nature Physics, Published online: 07 February 2022; doi:10.1038/s41567-021-01487-7

Physical systems with continuous degrees of freedom can be used to implement quantum error correction codes. An autonomous correction protocol has now been used to extend the lifetime of a qubit encoded in the motion of a trapped ion.

Cyclotron resonance overtones and near-field magnetoabsorption via terahertz Bernstein modes in graphene

Nature Physics, Published online: 07 February 2022; doi:10.1038/s41567-021-01494-8

Electrons in an external magnetic field absorb electromagnetic radiation via cyclotron resonance. Deviations from this behaviour in the form of overtone resonances due to ultraslow magnetoplasmonic excitations are now reported for graphene.

Sequence-dependent surface condensation of a pioneer transcription factor on DNA

Nature Physics, Published online: 03 February 2022; doi:10.1038/s41567-021-01462-2

A DNA-binding protein condenses on DNA via a switch-like transition. Surface condensation occurs at preferential DNA locations suggesting collective sequence readout and enabling sequence-specificity robustness with respect to protein concentration.
