Axions are hypothetical particles that were proposed to solve the strong charge–parity
problem in high-energy physics. Although they have long been known in quantum field …

The discoveries of intrinsically magnetic topological materials, including semimetals with a
large anomalous Hall effect and axion insulators,–, have directed fundamental research in …

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

Weyl semimetals are topological materials whose electron quasiparticles obey the Weyl
equation. They possess many unusual properties that may lead to new applications. This is …

Objects around us constantly emit and absorb thermal radiation. The emission and
absorption processes are governed by two fundamental radiative properties: emissivity and …

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 …

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 …

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 …

Thermal diodes, which allow heat transfer in a preferential direction while being blocked in a
reverse direction, have numerous applications in thermal management, information …

We theoretically investigate a nonlinear spin Hall effect in PT-symmetric antiferromagnetic
metals, which serve as an efficient spin current generator. We elucidate that an emergent …
