Fig. 4: Fermi arcs and chiral quasiparticle interference.

a Constant energy cuts at E = 450 meV for the two different PdGa(001) enantiomers. b Theoretically calculated FT scattering maps. c-e constant energy cuts and their relative scattering pattern by progressively including: c only one Fermi arc; d one Fermi arc and trivial states; e all Fermi arcs.
