Surface alloys, surface rumpling and surface stress
Surface Science, 2004Abstract The results of density functional theory calculations of the surface structure and surface stress of a series of 13 different surface alloy phases for which there are quantitative experimental structure determinations are presented, 12 involving alloying adsorbate atoms (Au, Pd, Bi, Sn, Mg, Pb) with larger atomic radii than those of the ...

Surface-surface phonon scattering by surface inhomogeneities
Journal of Physics: Condensed Matter, 1992A one-dimensional model is presented for surface phonon scattering into surface phonon channels by atomic inhomogeneities along a high symmetry direction in a solid surface. The model yields characteristic resonances over the full Brillouin zone of the model linear chain, for a monoatomic step and an adatom, at the limit of low concentrations where the

Recent work using high resolution angle-resolved photoemission to determine the Fermi surfaces for surface-localized electronic levels on several metal surfaces is reviewed. We examine our fundamental motivation for these studies and their relation to phenomena observed in other branches of chemistry and physics.

Summary: A Fuchsian group is a discrete subgroup of \(\text{PSL}(2,\mathbb{R})\). As such it acts discontinuously on \(\mathbb{H}^2\) (the upper half plane model of the hyperbolic plane) by fractional linear transformations. This action induces an action on the real line.

Surface forces and surface interactions
Journal of Colloid and Interface Science, 1977Abstract This paper discusses briefly some of the theoretical problems relating to surface problems as seen by an experimental physicist. In particular, questions are raised concerning the calculation of interaction energies between condensed phases in atomic contact.

Atoroidal Surface Bundles Over Surfaces
Geometric and Functional Analysis, 2009A `surface group' is the fundamental group of a closed orientable surface other than the 2-sphere. A `surface-by-surface group' is a group \(G\) with a normal subgroup \(N\), such that both \(N\) and \(G/N\) are surface groups. They are referred to as `fibre' and `base' groups, respectively.

Surfaces and surface metrology
International Journal of Precision Technology, 2013This paper discusses manufacturing methods for surfaces of simple to freeform geometry and the need to control the form and surface topography. Measurement techniques for assessment of form error and surface topography are outlined. At the end, engineered surfaces are taken and examined in the same context.

Multiconic surfaces are a generalization of the type of surface called polyconic in numerical control of machine tools. The general theory is developed in this paper using a new parametrization. In the original form there was a problem as to whether or not a point that satisfies surface equations actually belonged to the intended surface.

Two cases of surface dyslexia are described. In this disorder, irregular words such as broad or steak are less likely to be read aloud correctly than regularly-spelled words like breed or steam; and when irregular words are misread the incorrect response is often a regularisation (reading broad as “brode” and steak as “steek, for example).
