Machine learning glasses

Mon, 06/04/2020 - 00:00

Nature Physics, Published online: 06 April 2020; doi:10.1038/s41567-020-0873-1

Artificial neural networks now allow the dynamics of supercooled liquids to be predicted from their structure alone in an unprecedented way, thus providing a powerful new tool to study the physics of the glass transition.

Electronic correlations in nodal-line semimetals

Nature Physics, Published online: 06 April 2020; doi:10.1038/s41567-020-0859-z

What happens to topological materials when their electrons are strongly interacting is an open question. Shao and others demonstrate that ZrSiSe is a material that can address this as it has a topological band structure and non-trivial correlations.

Unveiling the predictive power of static structure in glassy systems

Nature Physics, Published online: 06 April 2020; doi:10.1038/s41567-020-0842-8

The physics that underlies the glass transition is both subtle and non-trivial. A machine learning approach based on graph networks is now shown to accurately predict the dynamics of glasses over a wide range of temperatures, pressures and densities.

Black holes associated with cosmic neutrino flares

Nature Physics, Published online: 06 April 2020; doi:10.1038/s41567-020-0864-2

Astrophysical neutrinos could originate from blazars, but their modelling is challenging. Instead, the source of cosmic neutrinos could be a special yet unidentified class in which jets burrow through stellar material and produce neutrinos.

Nature Physics, Published online: 06 April 2020; doi:10.1038/s41567-020-0876-y

The impending update to the European Strategy for Particle Physics is an apt moment to chart the future of the field — a future that should be supported and ensured.

Cooking with quantum gas

Nature Physics, Published online: 30 March 2020; doi:10.1038/s41567-020-0861-5

An ultra-cold atomic gas is used to image a phase transition in an iron pnictide with micrometre resolution.

Nematic transitions in iron pnictide superconductors imaged with a quantum gas

Mon, 30/03/2020 - 00:00

Nature Physics, Published online: 30 March 2020; doi:10.1038/s41567-020-0826-8

A trapped quantum gas and optical microscopy are simultaneously employed to measure the nematicity of an iron-based superconductor. This demonstrates the potential of quantum gases to be used for scanning microscopy of quantum materials.

Quantum metasurfaces with atom arrays

Mon, 30/03/2020 - 00:00

Nature Physics, Published online: 30 March 2020; doi:10.1038/s41567-020-0845-5

A kind of quantum metasurface made of an atom array is proposed, providing the possibility to control both spatiotemporal and quantum properties of transmitted and reflected light.

A rare quantum leap

Nature Physics, Published online: 30 March 2020; doi:10.1038/s41567-020-0871-3

Single rare-earth ions are hard to observe and even harder to use as qubits. However, with the help of coupling to an optical cavity and clever engineering of selection rules, a big step has been taken to establish their new role in the quantum world.

Flexible filaments buckle into helicoidal shapes in strong compressional flows

Mon, 30/03/2020 - 00:00

Nature Physics, Published online: 30 March 2020; doi:10.1038/s41567-020-0843-7

A general mechanism through which elastic filaments suspended in a strong compressional flow buckle and spontaneously acquire a chiral helicoidal shape is uncovered and elucidated theoretically.

Nature Physics, Published online: 30 March 2020; doi:10.1038/s41567-020-0846-4

The quark–gluon plasma, in which quarks and gluons are deconfined, is a transient state created in collisions of heavy nuclei. By defining an effective temperature, this temperature and the system’s entropy density and speed of sound are determined.

Nature Physics, Published online: 30 March 2020; doi:10.1038/s41567-020-0825-9

Placing two Bernal-stacked graphene bilayers on top of each other with a small twist angle gives correlated states. As the band structure can be tuned by an electric field, this platform is a more varied setting to study correlated electrons.

Nature Physics, Published online: 23 March 2020; doi:10.1038/s41567-020-0854-4

Determining the properties that emerge from the equations that govern turbulent flow is a fundamental challenge in non-equilibrium physics. A hydrodynamic theory for two-dimensional active nematic fluids at vanishing Reynolds number is now put forward, revealing a universal scaling behaviour for this class of systems.
