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 …

The temperature distribution on a rotating cylindrical shell in the presence of a primary radiative source and a reflecting and radiating infinite plane
… solution to the linear equation is found by the Green's function technique. Then some numerical results are obtained for variations in the non-dimensional parameters.

Comparison of smallest eigenvalues and extremal points for third and fourth order three point boundary value problems.
… methods. One method involves finding the Green's function for –u⁽ⁿ⁾ = 0 satisfying the higher order boundary conditions, and the other involves making a substitution that allows us to work with a variation of the fourth order problem. Extremal points via Krein-Rutman theory are then found. …

Theory of carrier transport in III-Nitride based heterostructures
… systems. More specifically, the non-equilibrium Green's function (NEGF) formalism has been employed to study ballistic transport in a fully quantum mechanical setting. This builds on a tight-binding description of the electronic structure which ensures an atomistic description of the alloy is …

Dilute nitride semiconductors : band structure, scattering and high field transport
… of GaNxAs1−x, where this gap is filled in the Green’s function model. Therefore we develop a self-consistent Green’s function (SCGF) approach, which provides excellent agreement with supercell calculations and reveals a gap in the DOS, in contrast with the results of previous …

Ambient seismic noise tomography of the southern United States and seismic inversion with dictionary learning using unsupervised machine learning.
… and regional networks) to estimate the Empirical Green’s Function (EGF) through cross-correlation and cross-coherence. This mimics Rayleigh wave phase characteristics. We address the problem of non-stationary phases in Rayleigh wave extraction from ambient noise. Seismic interferometry assumes …
