Reentrant topological phase in half-Heusler compounds

Physical Review Materials
Half-Heusler compounds are known for their various compositions and multifunctional properties including topological phases. In this study, we investigate the topological classification of this class of materials based on the ordering of the $Γ_6$, $Γ_8$ states, and a previously overlooked $Γ_6^*$ state, during an adiabatic expansion process.
