Investigations of the exchange energy of neutral atoms in the large-Z limit
Jeremy J. Redd, Antonio C. Cancio, Nathan Argaman +1
The non-relativistic large- expansion of the exchange energy of neutral atoms provides an important input to modern non-empirical density functional approximations. Recent works…
Leading correction to the local density approximation for exchange in large- atoms
Nathan Argaman, Jeremy Redd, Antonio C. Cancio +1
The large- asymptotic expansion of atomic energies has been useful in determining exact conditions for corrections to the local density approximation in density functional theor…
Bond-counting potentials -- A classical many-body model of covalent bonding with exact solutions in one dimension
Shlomi Matityahu, Nathan Argaman
We introduce "bond-counting" potentials, which provide an elementary description of covalent bonding. These simplistic potentials are intended for studies of the mechanisms behind…
Fractional occupation in Kohn-Sham density-functional theory and the treatment of non-pure-state v-representable densities
Eli Kraisler, Guy Makov, Nathan Argaman +1
In the framework of Kohn-Sham density-functional theory, systems with ground-state densities that are not pure-state v-representable in the non-interacting reference system (PSVR)…
