In a significant development in the field of superconductivity, researchers at The University of Manchester have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving superconductivity in the quantum Hall regime, a longstanding challenge in condensed matter physics.

By precisely visualizing the structure and transformations in penta-twinned nanoparticles and interpreting this information with the help of atomic-scale simulations, researchers were able to detail the interplay between surface diffusion, tensile strain relaxation, morphology evolution, and detwinning more clearly. This insight can help guide future efforts in controlling twinning and detwinning in gold nanoparticles.

The material’s very tiny crinkles are the perfect size for young bone cells and immune cells to latch onto. With their firmer grip on the coatings, human cells can strongly adhere to the implant and stretch out along its surface. Stretched bone cells develop faster, and stretched immune cells tend to help heal tissue and reduce inflammation rather than attack the implant as a foreign invader, so the researchers think their coatings could make medical implants more successful.

Researchers at the University of São Paulo (USP) in Brazil have developed a bioelectronic chip that simultaneously detects vitamins C and D in body fluids. It is flexible and easy to use, and can be adapted for use in a wearable device to assist with a personalized diet. Details are described in an article published in ACS Applied Nano Materials, and featured on the cover of the journal.

Naturally occurring bacteria also use conductive filaments, known as nanowires, to transfer electrons across their membranes. Importantly, bacterial nanowires that conduct electricity have the potential to interact with biological systems, such as living cells, and could be used in biosensing to monitor internal signals from the body using a human-machine interface.

Led by FLEET at Monash University, a new study (published this week in Nature Communications) has demonstrated a Mott insulating phase within an atomically-thin metal-organic framework (MOF), and the ability to controllably switch this material from an insulator to a conductor. This material’s ability to act as an efficient ‘switch’ makes it a promising candidate for application in new electronic devices such as transistors.

It could be used, for example, to build an nuclear clock that could measure time more precisely than the best atomic clocks available today. It could also be used to answer completely new fundamental questions in physics - for example, the question of whether the constants of nature are actually constant or whether they change in space and time.

Nonvolatile magnetic memory devices are crucial for various electronic applications as they retain stored information even when power is turned off. With their unique composition of single ferromagnetic and ferroelectric domains, BFCO 60-nm nanodots show great potential for creating magnetic memory devices that require minimal electrical power for writing and reading operations.

In a large quantum system comprising many interconnected parts, one can think about entanglement as the amount of quantum information shared between a given subsystem of qubits (represented as spheres with arrows) and the rest of the larger system. The entanglement within a quantum system can be categorized as area-law or volume-law based on how this shared information scales with the geometry of subsystems.

In an effort to understand how and why 2D interfaces take on the structures they do, researchers at the University of Illinois Urbana-Champaign have developed a method to visualize the thermally-induced rearrangement of 2D materials, atom-by-atom, from twisted to aligned structures using transmission electron microscopy (TEM). They observed a new and unexpected mechanism for this process where a new grain was seeded within one monolayer, whose structure was templated by the adjacent layer. Being able to control the macroscopic twist between layers allows for more control over the properties of the entire system.

The ability to share quantum information is crucial for developing quantum networks for distributed computing and secure communication. Quantum computing will be useful for solving some important types of problems, such as optimising financial risk, decrypting data, designing molecules, and studying the properties of materials.

A new technique, called advanced dual-chirped optical parametric amplification, has increased the energy of single-cycle laser pulses by a factor of 50. The technique uses two crystals which amplify complementary regions of the spectrum.

A team led by Seigo Tarucha of the RIKEN Center for Emergent Matter Science has measured the noise between two silicon qubits that were 100 nanometers apart.

The new properties of goldene are due to the fact that the gold has two free bonds when two-dimensional. Thanks to this, future applications could include carbon dioxide conversion, hydrogen-generating catalysis, selective production of value-added #chemicals, #hydrogen production, #water purification, #communication, and much more.

Like conventional electronics, spintronics, or spin electronics, is based on electrons as information carriers. However, it uses not only their electrical charge but also another particle property – the spin, i.e., the quantum-mechanical intrinsic rotation. The advantage: In contrast to conventional electronics, the computing process does not require transporting electrical charges, which is inevitably associated with losses due to the heat generated in the material. Instead, the spin excitations are only passed from one electron to another, similar to a relay race. In principle, this allows information to travel more efficiently and with minimal losses as magnetic excitation races through the material as a spin wave.

Physicists at Julius-Maximilians-Universität Würzburg (JMU) have made a discovery that could boost the understanding of the role of entanglement in high-temperature copper oxide superconductors. The low-energy quasiparticles of these enigmatic quantum materials, so-called Zhang-Rice singlets, were found to be remarkably resilient against extreme disorder.

An international research team led by the University of Göttingen has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels. Furthermore, they have shown that the current can be “switched” on and off, which has potential for developing tiny, energy-efficient transistor.
