Eigenvalue comparison theorems for certain boundary value problems and positive solutions for a fifth order singular boundary value problem.
… to a cone in conjunction with sign properties of Green's functions. Finally, initial results are established for the existence of positive solutions for singular two point boundary value problems for a fifth order nonlinear differential equation. The methods involve application of a fixed point …

An SEGF study of the Rh(001) surface.
… has been performed using the surface embedded Green function method. Calculations have been performed by embedding a three-layer slab onto a bulk rhodium substrate. The calculated work function and surface core level shifts are in good agreement with other theoretical work. Additionally, bulk …

Phonon dispersion curves and atomic mean square displacement for several fcc and bcc materials
… perturbation theory (PT) and a recently proposed Green's function (GF) method by Shukla and Hiibschle. The latter method includes certain anharmonic effects to all orders of anharmonicity. In order to determine the effect of the range of the interatomic interaction upon the anharmonic …

Computational modeling of defects in nanoscale device materials
… (CNTs) are studied using DFT in conjunction with Green’s function based techniques. The latter are applied to evaluate the low-temperature, low-bias Landauer conductance spectrum from which mesoscopic transport properties such as the elastic mean free path and localization length of …
