Magnetism meets topology on a superconductor's surface

Electrons in a solid occupy distinct energy bands separated by gaps. Energy band gaps are an electronic "no man's land," an energy range where no electrons are allowed. Now, scientists studying a compound containing iron, ...

Direct observation of coherence energy scale of Hund's metal

Strongly correlated systems are materials that exhibit strong interactions between electrons, a property unseen in ordinary conductors or insulators. Typical examples include metal-insulator transitions or unconventional ...

Super-resolution RNA imaging in live cells

Ribonucleic acid (RNA) is key to various fundamental biological processes. It transfers genetic information, translates it into proteins or supports gene regulation. To achieve a more detailed understanding of the precise ...

Moiré patterns facilitate discovery of novel insulating phases

Materials having excess electrons are typically conductors. However, moiré patterns—interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern—can ...

Kagome graphene promises exciting properties

Researchers around the world are searching for new synthetic materials with special properties like superconductivity—that is, the conduction of electric current without resistance. These new substances are an important ...

Spreading focus for better imaging

Extreme Ultraviolet (EUV) light in microscopy offers the advantage of obtaining a high-resolution image combined with spectral information about the object under study. However, because EUV microscopy uses diffraction instead ...
