Topological transitions to Weyl states in bulk Bi${}_2$Se${}_3$: Effect of hydrostatic pressure and doping

Sudip Kumar Saha, Hrishit Banerjee, Manoranjan Kumar

Bi${}_2$Se${}_3$, a layered three dimensional (3D) material, exhibits topological insulating properties due to presence of surface states and a band gap of 0.3 eV in the bulk. We study…
