Abstract
Based on k · p analysis and realistic tight-binding calculations, we find that time-reversal-breaking Weyl semimetals can be realized in magnetically-doped (Mn, Eu, Cr, etc.) Sn1-xPbx (Te, Se) class of topological crystalline insulators. All theWeyl points are well separated in momentum space and possess nearly the same energy due to high crystalline symmetry. Moreover, both the Weyl points and Fermi arcs are highly tunable by varying Pb/Sn composition, pressure, magnetization, temperature, surface potential, etc., opening up the possibility of manipulating Weyl points and rewiring the Fermi arcs.
