A Step in the Direction of Resolving the Paradox of Perdew-Zunger Self-interaction Correction. II. Gauge Consistency of the Energy Density at Three Levels of Approximation
Puskar Bhattarai, Kamal Wagle, Chandra Shahi +7
The Perdew-Zunger(PZ) self-interaction correction (SIC) was designed to correct the one-electron limit of any approximate density functional for the exchange-correlation (xc) energ…

A Precision Measurement of the Neutron Scattering Length of He-4 Using Neutron Interferometry
R. Haun, F. E. Wietfeldt, M. Arif +5
We report a 0.08 % measurement of the bound neutron scattering length of He using neutron interferometry. The result is $b = (3.0982 \pm 0.0021 \mbox{ [stat]} \pm 0.0014 \mbox{…

Stretched or noded orbital densities and self-interaction correction in density functional theory
Chandra Shahi, Puskar Bhattarai, Kamal Wagle +17
Semi-local approximations to the density functional for the exchange-correlation energy of a many-electron system necessarily fail for lobed one-electron densities, including not o…
