Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

Quantum materials hosting Weyl fermions have opened a new era of research in condensed
matter physics. First proposed in 1929 in the context of particle physics, Weyl fermions have …

The nonlinear Hall effect (NLHE), the phenomenon in which a transverse voltage can be
produced without a magnetic field, provides a potential alternative for rectification or …

The reciprocity between thermal emission and absorption in materials that satisfy the
Lorentz reciprocity places a fundamental constraint on photonic energy conversion and …

Macroscopic responses of magnets are often governed by magnetization and, thus, have
been restricted to ferromagnets. However, such responses are strikingly large in the newly …

Initiated by the discovery of topological insulators, topologically non-trivial materials have
attracted immense interest in the physics community in the past decade. One of the latest …

Flat-band materials such as the kagome metals or moiré superlattices are of intense current
interest. Flat bands can result from the electron motion on numerous (special) lattices and …

Spectroscopic detection of Dirac and Weyl fermions in real materials is vital for both,
promising applications and fundamental bridge between high-energy and condensed …

Superconductivity in topological materials has drawn significant interest from the scientific
community as these materials provide a hint of the existence of Majorana fermions …
