Handedness-dependent quasiparticle interference in the two enantiomers of the topological chiral semimetal PdGa

Handedness-dependent quasiparticle interference in the two enantiomers of the topological chiral semimetal PdGa

Direct visualization of chiral effects in topological chiral semimetals remains elusive. Here, Sessi et al. demonstrate that quasiparticle scattering at impurities in the two enantiomers of PdGa gives rise to handedness dependent quantum interference patterns.
