Trigonal tellurium, a small-gap semiconductor with pronounced magneto-electric and
magneto-optical responses, is among the simplest realizations of a chiral crystal. We have …

In the ferromagnetic (FM) Weyl semimetal CeAlSi both space-inversion and time-reversal
symmetries are broken. Our quantum oscillation (QO) data indicate that the FM ordering …

Recently, phonons with chirality (chiral phonons) have attracted significant attention. Chiral
phonons exhibit angular and pseudoangular momenta. In circularly polarized Raman …

Elemental tellurium is a strongly spin-orbit coupled Peierls-distorted semiconductor whose
band structure features topologically protected Weyl nodes. Using time-dependent density …

Relativistic Weyl fermion quasiparticles in Weyl semimetal bring the electron's chirality
degree of freedom into the electrical transport and give rise to exotic phenomena. A …

Topological semimetals in chiral crystals, which possess both structural handedness and
band crossings (or nodes) with topological chiral charge, exhibit many exotic physical …

The Weyl semimetal CeAlGe is a promising material to study nontrivial topologies in real
and momentum space due to the presence of a topological magnetic phase. Our results at …

Utilizing in situ Raman spectroscopy, resistivity, and Hall-effect measurements, we
conducted an extensive investigation on the continuous electronic phase transitions and …

Ideal Weyl semimetals, with minimum Weyl nodes located far away from each other in
reciprocal space and near the Fermi level in the energy space, are considered to be crucial …
