Fluid interfacial energy drives the emergence of three-dimensional periodic structures in micropillar scaffolds

Δευ, 22/03/2021 - 00:00

Nature Physics, Published online: 22 March 2021; doi:10.1038/s41567-021-01204-4

The revelation that fluid–fluid interfacial energy can drive structure formation in micropillar scaffolds offers a scalable way of synthesizing soft composites, which may have applications in building materials that mimic biological tissue.

Quantum coherence confined

Nature Physics, Published online: 18 March 2021; doi:10.1038/s41567-021-01211-5

Excitations confined by long-range interactions between Ising spins may provide a way for systems to escape thermalization. A quantum simulator made of trapped ions has now made such confinement-induced enhancement possible.

Domain-wall confinement and dynamics in a quantum simulator

Nature Physics, Published online: 18 March 2021; doi:10.1038/s41567-021-01194-3

Long-range Ising interactions present in one-dimensional spin chains can induce a confining potential between pairs of domain walls, slowing down the thermalization of the system. This has now been observed in a trapped-ion quantum simulator.

High-throughput injection–acceleration of electron bunches from a linear accelerator to a laser wakefield accelerator

Πέμ, 18/03/2021 - 00:00

Nature Physics, Published online: 18 March 2021; doi:10.1038/s41567-021-01202-6

Previously, injections from a conventional accelerator into a plasma-based one suffered from low coupling efficiencies. Now electron bunches are injected with an efficiency of nearly 100% into a laser wakefield accelerator without loss of charge.

Detection of Kardar–Parisi–Zhang hydrodynamics in a quantum Heisenberg spin-1/2 chain

Nature Physics, Published online: 11 March 2021; doi:10.1038/s41567-021-01191-6

Quantum systems possessing conserved quantities are expected to show quantum fluid properties governed by hydrodynamic equations. This behaviour is now evidenced in a neutron scattering study on the one-dimensional Heisenberg antiferromagnet KCuF3.

Reduced Hall carrier density in the overdoped strange metal regime of cuprate superconductors

Nature Physics, Published online: 11 March 2021; doi:10.1038/s41567-021-01197-0

A study of the high-field Hall coefficient in thallium- and bismuth-based single-layer cuprates demonstrates a smooth evolution of this quantity from p to 1 + p over a wide doping range.

A year on from the last-minute cancellation of the 2020 American Physical Society March Meeting, we examine the ups and downs of the online conference experience that has become the new normal during the COVID-19 pandemic.

Topology and superconductivity on the edge

Nature Physics, Published online: 08 March 2021; doi:10.1038/s41567-021-01190-7

Passing a supercurrent through a topological material can highlight the existence of higher-order boundary states, and may lead to applications in topological superconductivity.

The virtual photons that are exchanged when a free-electron vortex beam interacts with a nanoscopic target unlock an explicit connection between polarized optical spectroscopy and the inelastic scattering of scalar electron waves.

Nature Physics, Published online: 04 March 2021; doi:10.1038/s41567-021-01163-w

The functionality of electron energy loss spectroscopy can be extended to include a polarization analogue constructed via the dipole transition vector between two electronic states, bringing it closer to its optical counterpart.

Split superconducting and time-reversal symmetry-breaking transitions in Sr<sub>2</sub>RuO<sub>4</sub> under stress

When strain is applied to strontium ruthenate, superconductivity emerges at a different temperature to the breaking of time-reversal symmetry. This indicates that the superconductivity could have a chiral d-wave order parameter.

In magic-angle twisted bilayer graphene, topological Chern bands that are driven by electron–electron interactions appear at all the integer fillings of the moiré unit cell. The Rashba-like higher-energy bands also show Landau-level crossings.

Multiplexing increases the capacity of optical communication, but it is limited by the number of modes and their orbital angular momentum. A robust vortex laser now solves this problem by emitting several beams, all carrying large topological charges.
