Weyl semimetals are characterized by their electronic structure, where conduction and valence bands touch at points called Weyl nodes. These nodes occur in pairs with opposite chirality, leading to ...

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 ...

(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 ...

Theoretical and experimental work described in Nature Physics expands the repertoire of exotic phases of matter.

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 ...

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 ...

Scientists experimentally verify the existence of exotic surface conduction states in topological semimetals (TSMs), materials that lie at the boundary between conductors and insulators, by performing ...

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 ...

“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 ...

Quantum sensors can be used to reveal a surprising new mechanism for converting light into electricity in Weyl semimetals, Boston College Assistant Professor of Physics Brian Zhou and colleagues ...
