Original Paper


Superconducting properties of LaSn3 were calculated at ambient and applied positive hydrostatic pressure. The lattice structure of LaSn3 remained stable at ambient and all applied positive hydrostatic pressures due to the positive frequency of phonon dispersion plots for all modes of vibrations. The electron-phonon coupling constant (λep) and superconducting transition temperature (Tc) show an almost linear decrease with positive hydrostatic pressure. The majority of electron‑electron interaction is mediated by acoustic modes of vibration in comparison to optical modes of vibrations.

Calculations for LaSn3 at ambient pressure and all applied hydrostatic pressure were done at high performance computing facility (HPC) at IUAC, Delhi, and at National Param Supercomputing Facility (NPSF) at CDAC, Pune.
