Transmutation of the vicinal surface exponent due to gravity
(American Physical Society, 1988-04)
Near the edge of a facet, vicinal surfaces curve away from the plane with exponent (3/2. With gravity normal to the facet the exponent may change to 3. Generally, there will be a crossover from 3 to (3/2 as the facet edge ...
Extended and localized states in the periodic Anderson model
(American Physical Society, 1986-12)
The renormalized quasiparticle states are derived for a periodic Anderson model with a general hybridization matrix element between conduction electrons with two degrees of freedom and f electrons with N degrees of freedom. ...
Strongly correlated electron ground_state energy approximations for Anderson_like models
(American Institute of Physics, 1987-04-15)
We report preliminary results of convergence properties for nonperturbative resolvent approximations to Anderson_like models of magnetic ions in metals. Our study is initially focused on the spin_ 1/2 Anderson model for ...
Image transfer via color-coded projections
(Optical Society of America, 1983-07)
A technique is proposed whereby a 2-D distribution is transmitted via a set of 1-D projections. The color-coded projections are produced by illuminating the object with the dispersed spectrum of a white light source. They ...
Two competing interactions in the Anderson lattice model
(American Physical Society, 1987-04)
The vertex function of the SU(N) Anderson lattice model is calculated by treating the intersite coupling perturbatively. There are two different scattering processes that contribute to the effective interactions. In one ...
Curie temperature of PdFe films
(American Institute of Physics, 1984)
Ferromagnetic ordering of giant moments formed by dilute Fe in Pd host bulk alloys has been the subject of many investigations, but thin films have had little attention. Thin films exhibit evidence of a spin glass phase ...
On the zeros of the dispersion function in particle transport theory
(AIP Publishing, 1986-06)
The zeros of the dispersion function that arise in particle transport with anisotropicscattering are studied. An algebraic test for the number of zeros is presented.
Raman_scattering studies of silicon_implanted gallium arsenide: The role of amorphicity
(American Institute of Physics, 1986-03-15)
A series of Raman_scattering experiments were carried out on GaAsimplanted with Si+ and with SiF+ 3 ions, both before and after annealing, for samples subjected to fluences spanning a wide range. The implantation_induced ...
(e, 2e) spectrometer for investigating the spectral momentum density of thin-films
(AIP Publishing, 1984-08)
An (e, 2e) spectrometer has been constructed for detecting scattered and recoiling electrons from a thin solid film. The cross section for observing the two electrons in coincidence is proportional to the spectral momentum ...
Single-mode saturation of a linearly unstable plasma
(AIP Publishing, 1985)
The nonlinear oscillations of an electron plasma described by the collisionless Vlasov equation are studied using a perturbation technique previously applied by Simon and Rosenbluth [Phys. Fluids 1 9, 1567 (1976)]. It is ...
