Atmospheric Refraction Path Integrals in Ground-Based Interferometry
Richard J. Mathar
The basic effect of the earth's atmospheric refraction on telescope operation is the reduction of the true zenith angle to the apparent zenith angle, associated with prismatic aber…

Symmetry Analysis of the Kohn-Sham Band Structure of Bulk Lithium Fluoride
Richard J. Mathar
Kohn-Sham orbitals of face-centered cubic lithium fluoride are calculated in prototypical local-density approximations to the exchange-correlation functional. The symmetry analysis…

Electronic Stopping and Momentum Density of Diamond Obtained from First-Principles Calculations
Richard J. Mathar
We calculate the "head" element or the (0,0)-element of the wave-vector and frequency-dependent dielectric matrix of bulk crystals via first-principles, all-electron Kohn-Sham stat…
