The Convexity Condition of Density-Functional Theory
Andrew C. Burgess, Edward Linscott, David D. O'Regan
It has long been postulated that within density-functional theory (DFT) the total energy of a finite electronic system is convex with respect to electron count, so that 2 E_v[N_0]…

The tilted-plane structure of the energy of finite quantum systems
Andrew C. Burgess, Edward Linscott, David D. O'Regan
The piecewise linearity condition on the total energy with respect to the total magnetization of finite quantum systems is derived, using the infinite-separation-limit technique. T…
