Unbridled mental power, Published online: 02 January 2019; doi:10.1038/s41567-018-0388-1

Artificial intelligence is set to rival the human mind, just as the engine did the horse. José Hernández-Orallo looks at how we compare cognitive performance.

Analogue black-hole horizons

Analogue black-hole horizons, Published online: 17 December 2018; doi:10.1038/s41567-018-0367-6

Some gravitational phenomena are difficult or even impossible to observe in real spacetime. Laboratory analogues of black-hole horizons offer new perspectives on field theory effects that might help our understanding of gravitation.

Strain-tunable magnetism at oxide domain walls

Strain-tunable magnetism at oxide domain walls, Published online: 17 December 2018; doi:10.1038/s41567-018-0363-x

Ferromagnetism is observed at ferroelastic domain walls in strontium titanate and its heterostructures with other oxides. Applying strain can reverse the magnetism. This suggests the possibility of device engineering using domain walls.

The Goldstone mode and resonances in the fluid interfacial region, Published online: 10 December 2018; doi:10.1038/s41567-018-0361-z

Accurately capturing both microscopic and mesoscopic properties of fluid–gas interfaces is a long-standing challenge. Now, a microscopic theory of correlation functions that can be scaled up to explain mesoscopic surface tension phenomena is put forward.

Collective energy gap of preformed Cooper pairs in disordered superconductors, Published online: 10 December 2018; doi:10.1038/s41567-018-0365-8

Experiments show two different energy scales associated with the onset of superconductivity in an amorphous superconductor. This validates the theory of Cooper pairs that condense to a superfluid at lower temperature than they form.

Exchange-driven intravalley mixing of excitons in monolayer transition metal dichalcogenides, Published online: 10 December 2018; doi:10.1038/s41567-018-0362-y

Two-dimensional electronic spectroscopy experiments and first-principles many-electron calculations demonstrate the quantum mixing of different exciton states in monolayer MoS2. This reveals the many-body effects and dynamics of exciton formation in 2D materials.

Creation of quark–gluon plasma droplets with three distinct geometries, Published online: 10 December 2018; doi:10.1038/s41567-018-0360-0

A quark–gluon plasma is produced in proton–gold, deuteron–gold and helium–gold collisions. Observing elliptic and triangular flow in this nearly inviscid fluid from these different initial geometries provides a unique benchmark for hydrodynamic models.

Entanglement of single-photons and chiral phonons in atomically thin WSe2

Entanglement of single-photons and chiral phonons in atomically thin WSe<sub>2</sub>, Published online: 10 December 2018; doi:10.1038/s41567-018-0366-7

A ‘which-way’ scattering process can generate entanglement between single photons and collective chiral vibrations in two-dimensional tungsten diselenide. The result opens up ways for engineering non-reciprocal interactions at the quantum level.

The simulation of strongly correlated quantum phases using ultracold atoms in optical lattices was first proposed 20 years ago. In the wake of that pioneering idea, quantum simulations are now widely pursued in experiments across the world.

Modern physics edged mechanics out into the wilds of engineering. But multidisciplinary interest in pattern formation has moved it back into the mainstream, bringing with it interest from other fields — as this summer’s Solvay Workshop demonstrated.

Field-induced phase coexistence in an artificial spin ice

Field-induced phase coexistence in an artificial spin ice, Published online: 03 December 2018; doi:10.1038/s41567-018-0348-9

Artificial spin-ice materials are usually described by spins that are either up or down. Here, a new type of spin ice is fabricated where the spins can be in one of three states with different coexisting phases separated by a first-order transition.
