Observation of giant spin-split Fermi-arc with maximal Chern number in the chiral topological semimetal PtGa

Topological quasiparticle with higher Chern number is promising to realize large-quantized photogalvanic effect. Here, the authors observe splitting of both topological surface and bulk states in a chiral crystal PtGa, suggesting multifold fermions with a maximal Chern number of ±4.
