Pressure driven Weyl-topological insulator phase transition in Weyl semimetal SrSi_2

Using DFT-based first-principles calculations, we demonstrate the tuning of the electronic structure of Weyl semimetal SrSi_2 via external uniaxial strain. The uniaxial strain facilitates the opening of bandgap along Γ-X direction and subsequent band inversion between Si p and Sr d orbitals. Z_2 inv...
