Interplay between nuclear shell evolution and shape deformation revealed by the magnetic moment of 75Cu

Interplay between nuclear shell evolution and shape deformation revealed by the magnetic moment of <sup>75</sup>Cu, Published online: 21 January 2019; doi:10.1038/s41567-018-0410-7

The magnetic moment of the neutron-rich exotic 75Cu nucleus is measured using rare isotope beams with a high spin alignment, clarifying how the evolution of the nuclear shell and the shape deformations are connected.

Far out-of-equilibrium spin populations trigger giant spin injection into atomically thin MoS2

Far out-of-equilibrium spin populations trigger giant spin injection into atomically thin MoS<sub>2</sub>, Published online: 21 January 2019; doi:10.1038/s41567-018-0406-3

Efficient spin injection across ferromagnet/semiconductor interfaces is a major goal for future spintronic approaches. Ultrafast spectroscopy now reveals strong spin currents to be inducible in monolayer MoS2 by ultralow-intensity laser pulses.

Evolution of charge order topology across a magnetic phase transition in cuprate superconductors

Evolution of charge order topology across a magnetic phase transition in cuprate superconductors, Published online: 21 January 2019; doi:10.1038/s41567-018-0401-8

A new form of charge ordering is observed in a cuprate superconductor. At low doping, a fully rotationally symmetric ordering appears before becoming locked to the Cu–O bond directions at high doping. The link between charge correlations and fermiology give a perspective on the phase diagram.

Plasmaspheric hiss waves generate a reversed energy spectrum of radiation belt electrons

Plasmaspheric hiss waves generate a reversed energy spectrum of radiation belt electrons, Published online: 21 January 2019; doi:10.1038/s41567-018-0391-6

Observations reveal that electrons in Earth’s outer radiation belt possess a spectrum that partially rises with increasing energy, contrary to common beliefs. Plasma hiss waves scattered off electrons are found to be the origin of this phenomenon.

Evidence of a gate-tunable Mott insulator in a trilayer graphene moiré superlattice

Evidence of a gate-tunable Mott insulator in a trilayer graphene moiré superlattice, Published online: 21 January 2019; doi:10.1038/s41567-018-0387-2

Report of the likely observation of a Mott insulator in trilayer graphene with a moiré potential. The Mott state can be tuned between different filling fractions via gating, which will enable the careful study of this paradigmatic many-body state.

Two-dimensional spin liquid behaviour in the triangular-honeycomb antiferromagnet TbInO3

Two-dimensional spin liquid behaviour in the triangular-honeycomb antiferromagnet TbInO<sub>3</sub>, Published online: 21 January 2019; doi:10.1038/s41567-018-0407-2

Detailed neutron scattering, magnetic susceptibility and muon spin relaxation studies indicate the absence of long-range magnetic order in the quantum magnet TbInO3 down to 0.46 K— an observation consistent with quantum spin liquid behaviour.

Chip-integrated visible–telecom entangled photon pair source for quantum communication

Chip-integrated visible–telecom entangled photon pair source for quantum communication, Published online: 21 January 2019; doi:10.1038/s41567-018-0394-3

Efficient photon pair sources connecting visible and telecommunication spectral regions are essential for viable long-distance fibre optic quantum communication architectures. A nanophotonic device is presented that allows kilometre-scale time–energy entanglement as an application.

Leggett mode controlled by light pulses, Published online: 21 January 2019; doi:10.1038/s41567-018-0385-4

There has latterly been a renewed interest in collective excitations in condensed matter systems. Now, spectroscopic evidence for the so-called Leggett mode is revealed in the superconductor MgB2.

Direct observation of ion acceleration from a beam-driven wave in a magnetic fusion experiment, Published online: 14 January 2019; doi:10.1038/s41567-018-0389-0

A major challenge for achieving useful thermonuclear fusion regimes is heating plasma to reactive temperature conditions. It is demonstrated experimentally how energetic ions, generated via neutral beam injection, can be exploited for this process.

Topological marker currents in Chern insulators, Published online: 14 January 2019; doi:10.1038/s41567-018-0390-7

While topological states are often characterized by their global properties related to the topological invariants, the introduced real-space topological markers provide new insights to these states.

Quantum interference in second-harmonic generation from monolayer WSe2

Quantum interference in second-harmonic generation from monolayer WSe<sub>2</sub>, Published online: 07 January 2019; doi:10.1038/s41567-018-0384-5

Quantum interference between electronic pathways is generally difficult to observe in solid-state systems. Such interference is, however, now characterized in the second-harmonic generation from transition metal dichalcogenides, even at room temperature.

Highly efficient double ionization of mixed alkali dimers by intermolecular Coulombic decay

Highly efficient double ionization of mixed alkali dimers by intermolecular Coulombic decay, Published online: 07 January 2019; doi:10.1038/s41567-018-0376-5

Using alkali metal dimers attached to helium droplets, a new decay mechanism for intermolecular Coulombic decay is demonstrated. The process leads to previously unresolved double ionization for excitation energies exceeding double ionization energies.
