Double charge wave

Nature Physics - 21 hours 16 min ago

Nature Physics, Published online: 30 November 2021; doi:10.1038/s41567-021-01457-z

Charge density waves are the periodic spatial modulation of electrons in a solid. A new experiment reveals that they can originate from two different electronic bands in a prototypical transition metal dichalcogenide, NbSe2.

No need to decide

Nature Physics, Published online: 25 November 2021; doi:10.1038/s41567-021-01380-3

Information theory sets an upper limit on the ability of bacteria to navigate up chemical gradients. Experiments reveal that cells do so at speeds within a factor of two of the limit, suggesting they are selected to efficiently use information.

Precision mass measurement of lightweight self-conjugate nucleus <sup>80</sup>Zr
