Electrical charging overcomes the bouncing barrier in planet formation

Mon, 09/12/2019 - 00:00

Nature Physics, Published online: 09 December 2019; doi:10.1038/s41567-019-0728-9

In our understanding of planetary formation, it is still unclear how millimetre-sized dust grains grow into centimetre-sized aggregates. Microgravity experiments now show that electrical charging of the grains leads to the formation of larger clumps.

Charge on collision

Nature Physics, Published online: 02 December 2019; doi:10.1038/s41567-019-0758-3

Taking the expectation value of an observable is not the same as averaging over time.

A magnetic field boost for superconductors

Mon, 02/12/2019 - 00:00

Nature Physics, Published online: 02 December 2019; doi:10.1038/s41567-019-0731-1

High-magnetic-field experiments on the recently discovered unconventional superconductor UTe2 are consistent with p-wave pairing arising while time-reversal symmetry is broken. In turn, this suggests that this material is a candidate for a chiral superconductor that may be exploited for topological quantum computing.

Nature Physics, Published online: 02 December 2019; doi:10.1038/s41567-019-0722-2

The measurement of the dielectric constant combined with ab initio calculations of the polarizability and the virial coefficient of helium provides a new primary pressure standard, which is complementary to the mechanical standard.

A general method is proposed to calculate the out-of-time-ordered correlators (OTOCs) in one-dimensional systems. Motivated by the results obtained from its application to various systems, a universal form for the dynamics of OTOCs is conjectured.

Nature Physics, Published online: 11 November 2019; doi:10.1038/s41567-019-0705-3

Short pulses of light shift the balance between two competing charge density wave phases, allowing the weaker one to manifest transiently while suppressing the stronger one. This shows that competing phases can be tuned in a non-equilibrium setting.
