Abstract
Topological superconductors as characterized by Majorana surface states have been actively searched for their significance in fundamental science and technological implication. The large spin-orbit coupling in Bi-Pd binaries has stimulated extensive investigations on the topological surface states in these superconducting compounds. Here we report a study of normal-state electronic structure in a centrosymmetric within density functional theory calculations. By investigating the electronic structure from the bulk to slab geometries in this system, we predict that can host orbital-dependent and asymmetric Rashba surface states near the Fermi energy. This study suggests that will be a good candidate to explore the relationship between superconductivity and topology in condensed matter physics.
