Caltech scientists have developed an AI-based method that significantly accelerates calculations of quantum interactions among atomic vibrations (phonons) in materials, enabling 1,000 to 10,000 times faster analysis while maintaining accuracy, which could revolutionize the understanding of material properties and high-throughput screening.
Rice University scientists have discovered a 3D crystalline metal, a copper-vanadium-sulfur alloy, in which quantum correlations and crystal structure frustrate electron movement, resulting in a flat electronic band. The study, published in Nature Physics, details the theoretical design principle and experimental methodology used to find the material, which features a 3D pyrochlore lattice. The discovery may lead to new states of matter and potential applications, and the research team's predictive methodology could aid in identifying other materials with similar properties.
Researchers from MIT have discovered a unique configuration of five layers of graphene that exhibits a rare magnetic property called a "multiferroic" state, as well as a never-before-seen electronic behavior known as ferro-valleytricity. This arrangement of graphene layers allows for interactions between electrons, resulting in quantum effects and the emergence of preferred, ferroic orders. The material's multiferroic properties could have applications in energy-efficient magnetic storage devices capable of storing double the amount of information compared to conventional devices.
Researchers from Monash University have developed a new technique called the "quantum virial expansion" to study quantum impurities in 2D semiconductors. This approach allows for a more accurate description of the modified properties of quasiparticles formed by impurities. The method has shown remarkable agreement with experimental results and has the potential to reshape our understanding of complex quantum systems and unlock future applications using novel 2D materials.
