(a) Crystal structure of Bi/MnBi2Te4 vdW heterostructure. (b) Schematic diagram showing controllable magnetism and topological phase transition in the material. The magnetization orientation (Mi: i=x, y,z; red arrows) is tunable by applying strain (denoted by purple arrows) or magnetic field. QAH states with controllable Chern numbers are realized by changing the magnetization orientation or twisting […]
Credit: CC0 Public Domain Quantum technology is based on the engineering of devices that make use of the quantum properties of matter. One of the most prominent avenues of this technology is quantum computing, which may be able to leverage quantum bits (qubits) to perform calculations more efficiently than classical computers. Technology with this “quantum […]

Credit: Lunghammer – NAWI Graz Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air. A well-known example […]
Key Things to Know: Space-based communication, crucial for over 50 years, faces challenges such as signal delays, reduced bandwidth, and environmental interferences. SEN.COM, a UK-based firm, is set to demonstrate its advanced 4K video streaming technology from the International Space Station (ISS), aiming to provide unprecedented views of Earth and space. The technology developed by […]
