| contents | We report a first principles computational analysis of two phonon-mediated superconductors, In$_{5}$Bi$_{3}$ and In$_{5}$Sb$_{3}$. We show that spin-orbit coupling leads to splitting of electron bands around the Fermi energy, resulting in a suppression of the electronic density of states in both compounds. In In$_{5}$Bi$_{3}$, the spin-orbit coupling is essential for the dynamical stability of the experimentally observed phase, and the calculated superconducting critical temperature is in close agreement with measurements. In In$_{5}$Sb$_{3}$, the spin-orbit coupling significantly reduces the calculated superconducting critical temperature compared to calculations neglecting relativistic effects. Our work emphasises the subtle interplay between spin-orbit interactions and phonon-mediated superconductivity. |
