Query: New quantum phases of matter: Topological Materials   In this article, we provide an overview of the basic concepts of novel
topological materials. This new class of materials developed by combining the
Weyl/Dirac fermionic electron states and magnetism, provide a materials-science
platform to test predictions of the laws of topological physics. Owing to their
dissipationless transport, these materials hold high promises for technological
applications in quantum computing and spintronics devices.
