Experimental perspective on three-dimensional topological semimetals

BQ Lv, T Qian, H Ding - Reviews of Modern Physics, 2021 - APS
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 …

Cycling Fermi arc electrons with Weyl orbits

C Zhang, Y Zhang, HZ Lu, XC ** domain-wall topology in the magnetic Weyl semimetal CeAlSi
Y Sun, C Lee, HY Yang, DH Torchinsky, F Tafti… - Physical Review B, 2021 - APS
We report full vector map** of local magnetization in CeAlSi, a Weyl semimetal in which
both inversion and time-reversal symmetries are broken. The vector maps reveal …
