Researchers say an experimental approach for demonstrating the existence of an axionic behavior in specific materials may not have found it as previously reported. The multinational team was unable to ...

(Nanowerk Spotlight) Topology is the branch of mathematics that explores the nature of shapes independent of deformation. Physicists developed the concept of the phases of matter with properties that ...

Topological semimetals are one of the major discoveries in condensed-matter physics in recent years. The magnetic Weyl semimetal, in which the Weyl nodes can be generated and modulated by ...

Researchers have identified a class of quantum materials, called topological semimetals, that can split water into hydrogen fuel using nothing but sunlight, sidestepping the expensive platinum-based ...

Researchers from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS), in collaboration with researchers from the Institute of Semiconductors of CAS, revealed anomalous ...

The rapidly expanding class of quantum materials known as topological semimetals (TSMs) displays unique transport properties, including a striking dependence of resistivity on applied magnetic field, ...

Weyl semimetals are topological materials whose low-energy excitations obey the Weyl equation. In a Weyl semimetal, the conduction and valence bands touch at discrete points in momentum space called ...

“Contrary to topological insulators, topological semimetals possess a nontrivial chiral anomaly that leads to negative magnetoresistance and are hosts to both conductive bulk states and topological ...

A technical paper titled “Layered semimetal electrodes for future heterogeneous electronics” was published by researchers at IIT Madras and Indian Institute of Science Education and Research. Find the ...

An international team of scientists has discovered an exotic new form of topological state in a large class of 3D semi-metallic crystals called Dirac semimetals. The researchers developed extensive ...
