A direct approach to computing the non-interacting kinetic energy functional
Dharamveer Kumar, Amuthan A. Ramabathiran
The non-interacting kinetic energy functional, , plays a fundamental role in Density Functional Theory (DFT), but its explicit form remains unknown for arbitrary -re…

Analysis of quasi-planar defects using the Thomas--Fermi--von Weizsäcker model
Dharamveer Kumar, Amuthan A. Ramabathiran
We analyze the convergence of the electron density and relative energy with respect to a perfect crystal of a class of volume defects that are compactly contained along one directi…
