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.

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.

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, 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, 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, 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, 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.

Detecting the phonon spin in magnon–phonon conversion experiments, Published online: 02 April 2018; doi:10.1038/s41567-018-0079-y

Experiments on a magnetostrictive material reveal the conversion between coherent magnons and phonons that have spin.

Classical topological order in the kinetics of artificial spin ice, Published online: 02 April 2018; doi:10.1038/s41567-018-0077-0

Experiments on the Shakti geometry of artificial spin ice show that its low-energy excitations are topologically protected, and that an emergent classical topological order influences the ergodicity and equilibration of this nanomagnetic system.

Many particles — both fundamental and emergent — carry angular momentum or spin. Experiments have now demonstrated that phonons can transport angular momentum, showing that they may have spin too.

Light can be coupled to sound via Brillouin scattering, but realizing an efficient interaction isn’t trivial. A new type of resonator succeeds in doing so in a macroscopic device — boasting features that better its nanoscale counterparts.
