Frustration and thermalization in an artificial magnetic quasicrystal

Frustration and thermalization in an artificial magnetic quasicrystal, Published online: 11 December 2017; doi:10.1038/s41567-017-0009-4

Nanomagnets are often used to build artificial systems that are geometrically frustrated, but when quasiperiodic ordering is introduced, an unusual ground state can form, with an ordered skeletal structure surrounding groups of degenerate macrospins.

Signatures of a dissipative phase transition in photon correlation measurements, Published online: 11 December 2017; doi:10.1038/s41567-017-0020-9

Photon correlation measurements in driven-dissipative systems reveal the dynamical properties of dissipative phase transitions, as shown for optical bistability of cavity polaritons in GaAs.

Quantum criticality among entangled spin chains, Published online: 11 December 2017; doi:10.1038/s41567-017-0010-y

Exploiting the magnetic field-induced shift of entropy in certain molecular salts when going from 1D short-range ordering to a 3D quantum critical point could provide a route for producing strongly fluctuating quantum materials.

Quantum violation of an instrumental test

Quantum violation of an instrumental test, Published online: 11 December 2017; doi:10.1038/s41567-017-0008-5

Theory and experiment show that quantum correlations violate the instrumental test—a common statistical method used to estimate the strength of causal relationships between two variables.

Ligand-field helical luminescence in a 2D ferromagnetic insulator

Ligand-field helical luminescence in a 2D ferromagnetic insulator, Published online: 04 December 2017; doi:10.1038/s41567-017-0006-7

Atomically thin chromium tri-iodide is shown to be a 2D ferromagnetic insulator with an optical response dominated by ligand-field transitions, emitting circularly polarized photoluminescence with a helicity determined by the magnetization direction.

Attractive force on atoms due to blackbody radiation

Attractive force on atoms due to blackbody radiation, Published online: 04 December 2017; doi:10.1038/s41567-017-0004-9

The effect of blackbody radiation is expected to be very weak. The acceleration due to the attractive optical forces from blackbody radiation is measured in an atom interferometer and, surprisingly, it dominates gravity and radiation pressure

Strongly anisotropic spin relaxation in graphene–transition metal dichalcogenide heterostructures at room temperature

Strongly anisotropic spin relaxation in graphene–transition metal dichalcogenide heterostructures at room temperature, Published online: 04 December 2017; doi:10.1038/s41567-017-0019-2

Large spin–orbit coupling can be induced when graphene interfaces with semiconducting transition metal dichalcogenides, leading to strongly anisotropic spin dynamics. As a result, orientation-dependent spin relaxation is observed.

Symmetry-breaking spirals, Published online: 04 December 2017; doi:10.1038/s41567-017-0014-7

For a system to exhibit spiral patterns one would expect its parts to behave synchronously, as in a Mexican wave. Proving the contrary, chemical oscillators have now been observed in a state comprising a spiral surrounding an asynchronous core.

Topological valleytronics: Brought to light

Topological valleytronics: Brought to light, Published online: 04 December 2017; doi:10.1038/nphys4331

The topological valley Hall effect was predicted as a consequence of the bulk topology of electronic systems. Now it has been observed in photonic crystals, showing that both topology and valley are innate to classical as well as quantum systems.

Spiral wave chimera states in large populations of coupled chemical oscillators, Published online: 04 December 2017; doi:10.1038/s41567-017-0005-8

A spiral chimera state, composed by an ordered spiral surrounding a core of asynchronous oscillators, is revealed in a large grid of chemical oscillators.

Droplets moving on the surface of a vibrating fluid bath mimic the behaviour of electrons in quantum corrals. Introducing submerged features in the bath can even drive the droplets to excite modes that induce effects reminiscent of quantum mirages.

Diffraction and microscopy with attosecond electron pulse trains

Diffraction and microscopy with attosecond electron pulse trains, Published online: 27 November 2017; doi:10.1038/s41567-017-0007-6

Attosecond light pulses are used to probe ultrafast processes. The experimental observation of attosecond electron pulses now promises the marriage of these techniques with electron microscopy and diffraction.
