Attosecond coupled electron and nuclear dynamics in dissociative ionization of H2

Attosecond coupled electron and nuclear dynamics in dissociative ionization of H₂, Published online: 16 April 2018; doi:10.1038/s41567-018-0103-2

Attosecond XUV spectroscopy is reported, focussing on non-Born–Oppenheimer dynamics in molecular gases of light elements. It is shown that the phase of the detected photoelectrons carries information from both vibrational and electronic degrees of freedom.

Bose–Einstein condensation in a plasmonic lattice

Surface plasmon polaritons in an array of metallic nanoparticles evolve quickly into the band minimum by interacting with a molecule bath, forming a Bose–Einstein condensate at room temperature within picoseconds.

Spontaneous shear flow in confined cellular nematics

Spontaneous shear flow in confined cellular nematics, Published online: 16 April 2018; doi:10.1038/s41567-018-0099-7

Antiparallel streams of nematically oriented cells arise in both embryonic development and cancer. In vitro experiments and a hydrodynamic active gel theory suggest that these cells are subject to a transition that is driven by their activity.

Streams of motile cells appear in both healthy development and the evolution of tumours. A study of cells under lateral confinement now suggests their activity plays a key role in triggering these flows.

Amplification of intense light fields by nearly free electrons

Amplification of intense light fields by nearly free electrons, Published online: 16 April 2018; doi:10.1038/s41567-018-0105-0

Light fields of energy comparable to the Coloumb field that binds valence electrons in atoms generate states where nearly free electrons oscillate in the laser field. These are now shown to exist in rare gases, acting as gain for laser filamentation.

Charge quantum interference device

Charge quantum interference device, Published online: 09 April 2018; doi:10.1038/s41567-018-0097-9

The charge–phase duality in superconductors implies that the well-known SQUID has an analogue based on the interference of fluxons. Such a ‘charge quantum interference device’ (or CQUID) has now been experimentally demonstrated.

The push for a place in the crowd

The push for a place in the crowd, Published online: 09 April 2018; doi:10.1038/s41567-018-0114-z

Cells change shape and volume when they divide — not a simple task, especially when they are confined by surrounding tissue. Experiments now reveal that hydrostatic pressure changes generate the pushing forces that cells need to create space for division.

Mitotic cells generate protrusive extracellular forces to divide in three-dimensional microenvironments

Mitotic cells generate protrusive extracellular forces to divide in three-dimensional microenvironments, Published online: 09 April 2018; doi:10.1038/s41567-018-0092-1

Little is known about how a cell’s surroundings within tissue influence the mechanics of its division. Experiments on constrained dividing cells reveal that they create protrusive forces in order to undergo the shape changes required for division.

Elementary again

Elementary again, Published online: 06 April 2018; doi:10.1038/s41567-018-0108-x

Mark Keller explains how the elementary charge will soon be reinstated in metrology — and why it got sidelined in the first place.

Geometric constraints during epithelial jamming

Geometric constraints during epithelial jamming, Published online: 02 April 2018; doi:10.1038/s41567-018-0089-9

Epithelial cells are shown to scale via a shape distribution that is common to a number of different systems, suggesting that cell shape and shape variability are constrained through a relationship that is purely geometrical.

Bulk crystalline optomechanics

Bulk crystalline optomechanics, Published online: 02 April 2018; doi:10.1038/s41567-018-0090-3

Optomechanical coupling to macroscopic phonon modes of a bulk acoustic-wave resonator is demonstrated, providing access to high acoustics quality factors for phononic modes at high frequencies that are robust to decoherence.
