Twist engineering of the two-dimensional magnetism in double bilayer chromium triiodide homostructures

Πέμ, 02/12/2021 - 00:00

Nature Physics, Published online: 02 December 2021; doi:10.1038/s41567-021-01408-8

Stacking and twisting two-dimensional materials has led to the observation of a variety of electronic phenomena. Now, magnetic behaviour that is distinct from anything seen in individual layers is induced by a moiré pattern in double bilayer chromium triiodide.

Charge order and superconductivity in kagome materials

Nature Physics, Published online: 02 December 2021; doi:10.1038/s41567-021-01404-y

Superconductivity and ordered states formed by interactions—both of which could be unconventional—have recently been observed in a family of kagome materials.

Optomechanics joins the soliton club

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/s41567-021-01443-5

To test the validity of theoretical models, the predictions they make must be compared with experimental data. Instead of choosing one model out of many to describe mass measurements of zirconium, Bayesian statistics allows the averaging of a variety of models.

<i>Escherichia coli</i> chemotaxis is information limited

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

Nature Physics, Published online: 25 November 2021; doi:10.1038/s41567-021-01395-w

High-precision mass measurements of exotic zirconium nuclei are reported, and reveal a double-shell closure for the deformed nucleus 80Zr, which is more strongly bound than previously thought.

Developments in atomic control using ultracold magnetic lanthanides

Nature Physics, Published online: 25 November 2021; doi:10.1038/s41567-021-01398-7

The detailed structure of each atomic species determines what physics can be achieved with ultracold gases. This review discusses the exciting applications that follow from lanthanides’ complex electronic structure.

Quantum gas microscopy for single atom and spin detection

Nature Physics, Published online: 18 November 2021; doi:10.1038/s41567-021-01392-z

A search for axion-like dark matter with a quantum sensor that enhances potential signals is reported. This work constrains the parameter space of different interactions between nucleons and axion-like particles and between nucleons and dark photons.

Cell monolayers sense curvature by exploiting active mechanics and nuclear mechanoadaptation
