Magnetic topological materials represent a class of compounds with properties that are
strongly influenced by the topology of their electronic wavefunctions coupled with the …

Topological states of matter possess bulk electronic structures categorized by topological
invariants and edge/surface states due to the bulk-boundary correspondence. Topological …

Recently, Wang et al.[Phys. Rev. B 106, 195129 (2022) 2469-9950 10.1103/PhysRevB.
106.195129] challenged a widely held belief in the field of Weyl physics, demonstrating that …

The van der Waals compound, MnBi 2 Te 4, is the first intrinsic magnetic topological
insulator, providing a materials platform for exploring exotic quantum phenomena such as …

Topological semimetal states having the minimal number, ie, only a single pair, of Weyl
points are desirable for the study of effects associated with chiral topological charges. So far …

An underestimation of the fundamental band gap values by the density functional theory
within the local density approximation and associated approaches is a well-known …

Weyl semimetal is a unique topological phase with topologically protected band crossings in
the bulk and robust surface states called Fermi arcs. Weyl nodes always appear in pairs with …

We used angle-resolved photoemission spectroscopy (ARPES) and density functional
theory calculations to study the electronic properties of MnBi 2 Te 4, a material that was …

EuCd 2 As 2 is a magnetic semimetal that has the potential of manifesting nontrivial
electronic states, depending on its low temperature magnetic ordering. Here, we report the …

EuCd 2 As 2 is now widely accepted as a topological semimetal in which a Weyl phase is
induced by an external magnetic field. We challenge this view through firm experimental …
