Amorphous topological insulators constructed from random point sets

Amorphous topological insulators constructed from random point sets, Published online: 15 January 2018; doi:10.1038/s41567-017-0024-5

Whether spatial order is required for structures that support topological modes remains unclear. Amorphous arrangements of interacting gyroscopes suggest that topology arises in materials for which the only design principle is the local connectivity.

Superconductivity in few-layer stanene, Published online: 15 January 2018; doi:10.1038/s41567-017-0031-6

Stanene is a single sheet of tin atoms. Here, it is shown that a few stacked layers of stanene can be a superconductor. Changing the thickness of the substrate modifies the form of superconductivity and critical temperature.

Destabilizing turbulence in pipe flow

Destabilizing turbulence in pipe flow, Published online: 08 January 2018; doi:10.1038/s41567-017-0018-3

Turbulence in pipe flows causes substantial friction (and therefore economic) losses. An experimental and numerical study now shows a solution might be to initially enhance turbulent mixing, which subsequently leads to a collapse of turbulence.

Peace in the pipeline, Published online: 08 January 2018; doi:10.1038/s41567-017-0037-0

Turbulence in pipe flows causes substantial friction and economic losses. The solution to appease the flow through pipelines might be, counterintuitively, to initially enhance turbulent mixing and get laminar flow in return.

Enabled by recent advances in symmetry and electronic structure, researchers have observed signatures of unconventional threefold degeneracies in tungsten carbide, challenging a longstanding paradigm in nodal semimetals.

Three-component fermions with surface Fermi arcs in tungsten carbide, Published online: 08 January 2018; doi:10.1038/s41567-017-0021-8

Triply degenerate electronic structure—three-component fermions—protected by crystal symmetries is observed in tungsten carbide. The observed Fermi arcs associated with the surface states provide evidence of the non-trivial topology of the states.

Non-Hermitian physics and PT symmetry

Non-Hermitian physics and PT symmetry, Published online: 05 January 2018; doi:10.1038/nphys4323

This Review Article outlines the exploration of the interplay between parity–time symmetry and non-Hermitian physics in optics, plasmonics and optomechanics.

Economic complexity: From useless to keystone

Economic complexity: From useless to keystone, Published online: 05 January 2018; doi:10.1038/nphys4337

Technological innovation seems to be dominated by chance. But a new mathematical analysis suggests we might be able to anticipate when seemingly useless technologies become keystones of more complex environments.

Quantum teleportation, onwards and upwards, Published online: 05 January 2018; doi:10.1038/nphys4339

As we move beyond the twentieth anniversary of the teleportation of a quantum state, it's clear that the coming years will be just as fruitful.

It seems obvious that restricting travel should help prevent the surge of epidemics. But a new mathematical analysis now demonstrates that mobility often reduces the heterogeneity in population distributions, thereby lowering the epidemic risk.

Self-hybridization within non-Hermitian localized plasmonic systems, Published online: 01 January 2018; doi:10.1038/s41567-017-0023-6

A combined theoretical and experimental study of plasmonic nanostructures reveals a self-hybridization effect that arises from the non-Hermitian eigenmodes of localized surface plasmons.

Observation of dynamical vortices after quenches in a system with topology, Published online: 18 December 2017; doi:10.1038/s41567-017-0013-8

Non-equilibrium signatures of topology—the appearance, movement and annihilation of vortices in a cold-atom system—are identified, showing that topological phase can emerge dynamically from a non-topological state.

Coherent inflationary dynamics for Bose–Einstein condensates crossing a quantum critical point, Published online: 18 December 2017; doi:10.1038/s41567-017-0011-x

An ultracold quantum gas experiment shows that, when it crosses the many-body phase transition, the original ground state can evolve coherently into the new emergent phase, reflecting the initial global coherence presented in the system.

Critical regimes driven by recurrent mobility patterns of reaction–diffusion processes in networks, Published online: 18 December 2017; doi:10.1038/s41567-017-0022-7

Taking into account the spatial distribution of population and its mobility, a reaction–diffusion model of an epidemic process reveals several different critical regimes, in which human mobility may even be detrimental to the spread of the disease.

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.
