WebJan 31, 2024 · Pseudopotential models treat the electron–ion interaction using the second order perturbation theory which finally leads to interionic pair potentials [10,11,12,13,14]. Among different pseudopotential models, Ashcroft’s EMC and BS models have been widely used because of their success in studying different physical properties … The pseudopotential is an attempt to replace the complicated effects of the motion of the core (i.e. non-valence) electrons of an atom and its nucleus with an effective potential, or pseudopotential, so that the Schrödinger equation contains a modified effective potential term instead of the Coulombic potential term for core electrons normally found in the Schrödinger equation.
