topology

In recent years, scientists have been studying special materials called topological materials, with special attention paid to the shape, i.e., topology, of their electronic structures (electronic bands). Although it is not visible in real…

In the current issue of Nature Photonics, Prof. Dr. Oliver G. Schmidt, head of the Professorship of Material Systems for Nanoelectronics and Scientific Director of the Research Center for Materials, Architectures and Integration of…

In our quest for clean energy and sustainable health solutions, advanced materials with unique, customizable properties play a crucial role. Among them, a new generation of porous solids known as three dimensional (3D) covalent organic…

Microscopic materials analysis is essential to achieve desirable performance in next-generation nanoelectronic devices, such as low power consumption and high speeds. However, the magnetic materials involved in such devices often exhibit…

Topology and entanglement are two powerful principles for characterizing the structure of complex quantum states. In a new paper in the journal Physical Review X, researchers from the University of Pennsylvania establish a relationship…

Theoretical scientists have used topological mathematics and machine learning to identify a hidden relationship between nano-scale structures and thermal conductivity in amorphous silicon, a glassy form of the material with no repeating…

The new review paper on magnetic topological materials of Andrei Bernevig, Princeton University, USA, Haim Beidenkopf, Weizmann Institute of Science, Israel, and Claudia Felser, Max Planck Institute for Chemical Physics of Solids,…

A joint research team from the Hong Kong University of Science and Technology (HKUST) and the University of Tokyo discovered an unusual topological aspect of sodium chloride, commonly known as table salt, which will not only facilitate the…

Researchers at PSI have compared the electron distribution below the oxide layer of two semiconductors. The investigation is part of an effort to develop particularly stable quantum bits -and thus, in turn, particularly efficient quantum…

Losing particles can lead to positive, robust effects. An international collaboration has demonstrated a novel topology arising from losses in hybrid light-matter particles, introducing a new avenue to induce the highly-prized effects…
