In this study, we report a numerical scheme to integrate models for the kinetics of solidification processes together with phase-behavior computations in the context of continuum-scale hydrodynamic simulations. The objective of the phase-behavior com

We present quantitative theoretical studies of the wave-vector dependence of the cross section for excitation of surface plasmons by low-energy electrons incident on the Ag(100) surface. The analysis assumes the dipole mechanism provides the dominant

The first measurement of the temperature-dependent intrinsic linewidth of a surface phonon is reported. The linewidth of the vertically polarized L1-surface phonon of rare gas bilayer crystals is found to increase linearly with temperature. Anharmoni

The multiple scattering theory of High Resolution Electron Energy Loss Spectroscopy has been developed in the last decade. It has proved to be a very powerful tool in the study of surface lattice dynamics, since it predicts where the hard to observe

We explore the sensitivity of exchange asymmetries measured in spin-polarized low-energy electron diffraction to surface-magnetic-moment distribution, by comparing theoretical calculations to the data reported by Waller and Gradmann. We propose and t

We summarize results of our recent theoretical studies of spin dependent scattering of electrons from ferromagnetic surfaces. We obtain an excellent account of both the energy and angle variation of the exchange asymmetry reported by Waller and Gradm

We present calculations of spin-dependent electron-diffraction intensities from the Fe(110) surface. The results provide a good account of measurements on this surface reported by Waller and Gradmann. We use {ital ab} {ital initio} potentials generat

Using inelastic electron scattering we have determined the dispersion of surface phonons on the clean Ni(110) surface along the [001] ( Γ ¯ Y ¯ ), the [ 1 1 ¯ 0 ] ( Γ ¯ X ¯ ), and the [ 1 1 ¯ 1 ] ( Γ ¯ S ¯ ) direction. A lattice dynamical

It is shown that vibrational eigenvectors (outputs of a slab calculation) are not required for the calculation of high resolution electron energy loss spectra (EELS) or helium energy loss spectra. Instead, vibrational spectral densities (outputs of a

We discuss the lattice dynamics of rare-gas overlayers on metal surfaces, with attention to monolayers, bilayers, and trilayers on the Ag(111) surface. For this system, the adsorbate overlayers are incommensurate with the metal substrate. Our interes
