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.

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.

The intrinsic challenge for developing flexible QLED displays lies in the nature of quantum dots (QDs) themselves; as 0-D inorganic nanoparticles, they do not possess inherent stretchability. There have been some attempts to embed QDs within elastic materials to create a light-emitting and elastic composite material. A significant hurdle encountered during this approach was the elastomers' insulating properties, which impede the efficient injection of electrons and holes into the QDs, thereby diminishing the device's electroluminescent efficiency.

Magnetic nanographene, a tiny molecule composed of fused benzene rings, holds significant promise as a next-generation quantum material for hosting fascinating quantum spins due to its chemical versatility and long spin coherence time. However, creating multiple highly entangled spins in such systems is a daunting yet essential task for building scalable and complex quantum networks.

The discovery, published in the journal Nature, uses a novel technique using a type of interlocked molecule known as rotaxane. Under the influence of mechanical force - such as that observed at an injured or damaged site - this component triggers the release of functional molecules, like medicines or healing agents, to precisely target the area in need. For example, the site of a tumour.

Understanding water behavior in nanopores is crucial for both science and practical applications. Scientists from City University of Hong Kong (CityU) have revealed the remarkable behavior of water and ice under high pressure and temperature, and strong confinement. These findings, which defy the normal behavior observed in daily life, hold immense potential for advancing our understanding of water's unusual properties in extreme environments, such as in the core of distant ice planets. The implications of this major scientific advancement span various fields, including planetary science, energy science, and nanofluidic engineering.

The characterization of the dynamics of the excited states of a single atom localized on a surface remains to this day an experimental challenge. By combining a tunable pulsed laser at the junction of a low-temperature tunneling microscope, researchers have highlighted rapid photocurrent signals that can be attributed to the dynamics of excited states of an individual erbium atom deposited on the silicon surface.
