A direct approach to computing the non-interacting kinetic energy functional

Dharamveer Kumar, Amuthan A. Ramabathiran

The non-interacting kinetic energy functional, $T_{K S} (ρ)$ , plays a fundamental role in Density Functional Theory (DFT), but its explicit form remains unknown for arbitrary $N$ -rep…

Size-Dependent Power Laws for Edge Dislocations in Nickel Superalloys: A Molecular Dynamics Study

Divyeshkumar A. Mistry, Amuthan A. Ramabathiran

We present computational evidence using MD simulations of a size effect for the critical resolved shear stress (CRSS) of edge dislocation motion in nickel superalloys. We model the…
