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 …

Topological materials discovery has evolved at a rapid pace over the past 15 years following
the identification of the first nonmagnetic topological insulators (TIs), topological crystalline …

Topological semimetals feature protected nodal band degeneracies characterized by a
topological invariant known as the Chern number (C). Nodal band crossings with linear …

Unlike conventional Weyl nodes, unconventional ones carry a quantized monopole charge
C> 1, and their existence needs the protection of crystalline symmetries in addition to …

Chirality is an indispensable concept that pervades fundamental science and nature,
manifesting itself in diverse forms, eg, quasiparticles, and crystal structures. Of particular …

We investigate the nature of the linear-response tensors in planar Hall and planar thermal
Hall setups, where we subject a Rarita-Schwinger-Weyl (RSW) semimetal to the combined …

The discovery of topological semimetals with multifold band crossings has opened up a new
and exciting frontier in the field of topological physics. These materials exhibit large Chern …

Pyrite-structured PdSb 2 with the nonsymmorphic crystalline symmetry, has long been
predicted to host sixfold-degenerate exotic fermions beyond Dirac and Weyl. Although …

Non-Hermitian degeneracies are classified as defective exceptional points (EPs) and
nondefective degeneracies. While in defective EPs, both eigenvalues and eigenvectors …

We study, for the first time, the effects of strong short-range electron-electron interactions in
generic Rarita-Schwinger-Weyl semimetals hosting spin-3/2 electrons with linear dispersion …
