Since Nonmagnetic chiral crystals preserve the time-reversal symmetry, according to Kramers theorem, the spin up and down electronic states have to be degenerate on the time-reversal-invariant points. The quasiparticles around the degeneracy obey Weyl equations, and these new type of fermions are termed Kramers-Weyl fermions. This work has been published in Nature Materials 17, 978, (2018). The article is also highlighted in Nature Materials news & views. (doi: 10.1038/s41563-018-0210-6).
