Temperature and orientation dependence of kinetic roughening during homoepitaxy: A quantitative x-ray-scattering study of Ag
(American Physical Society, 1996)
Kinetic roughening during homoepitaxial growth was studied for Ag(111) and Ag(001). For Ag(111), from 150 to 500 K, the rms roughness exhibits a power law, σ∝tβ over nearly three decades in thickness. β≈1/2 at low temperatures, ...
On the Energy of Rotating Gravitational Waves
(arXiv, 1996)
A class of solutions of the gravitational field equations describing vacuum spacetimes outside rotating cylindrical sources is presented. A subclass of these solutions corresponds to the exterior gravitational fields of ...
Effects of Altered Prenatal Hormonal Environment on Expression of Autoimmune Disease in NZB/NZW Mice
(National Institute of Environmental Health Sciences, 1996)
F1 hybrid New Zealand Black (NZB) x New Zealand White (NZW) (NZB/NZW) mice spontaneously develop an autoimmune disease analogous to systemic lupus erythematosus (SLE) . Testosterone exerts a powerful suppressive effect on ...
Response-Dependence, Rigidification, and Objectivity
(Springer Verlag, 1996)
A response-dependent account of a given attribute, such as redness or wrongness, identifies the attribute with the disposition to produce specified sorts of response in specified sorts of being under specified conditions. ...
On the ionization of a Keplerian binary system by periodic gravitational radiation
(American Institute of Physics, 1996)
The gravitational ionization of a Keplerian binary system via normally incident periodic gravitational radiation of definite helicity is discussed. The periodic orbits of the planar tidal equation are investigated on the ...
Density‐functional studies of the electronic structure of the perovskite oxides: La1−xCaxMnO3
(American Institute of Physics, 1996)
Using density‐functional methods, we study the electronic structures of the lanthanum‐based ''double‐exchange'' perovskite magnets. Antiferromagnetic insulating solutions are obtained for both the end members, LaMnO3 and ...
Drag in Paired Electron-Hole Layers
(American Physical Society, 1996)
We investigate transresistance effects in electron-hole double-layer systems with a superfluid electron-hole condensate. Our theory is based on the use of a minimum dissipation premise to fix the current carried by the ...
Current-Dependent Exchange-Correlation Potential for Dynamical Linear Response Theory
(American Physical Society, 1996)
The frequency-dependent exchange-correlation potential, which appears in the usual Kohn- Sham formulation of a time-dependent linear response problem, is a strongly nonlocal functional of the density, so that a consistent ...
Collective modes and electronic spectral function in smooth edges of quantum hall systems
(American Physical Society, 1996)
We present a microscopic theory of the collective modes of a ''smooth'' edge of a quantum Hall system, showing under what conditions these modes can be described as a set of independent bosons. We then calculate the ...
Electrochemically assembled quasi-periodic quantum dot arrays
(Institute of Physics, 1996)
We describe two electrochemical self- assembly processes for producing highly ordered quasi-periodic arrays of quantum dots on a surface. The advantages of these techniques are: (i) they are `gentle' and do not cause ...

Quantum breathing mode for electrons with 1/r2 interaction
(American Physical Society, 1996)
We show that the collective excitation spectrum of electrons with 1/r2 interaction in a parabolic quantum dot of frequency ω0 contains a ''breathing'' mode of frequency 2Ω, where Ω2≡ω02+1/4ωc2 and ωc is the cyclotron ...
Gravitational Superenergy Tensor
(arXiv, 1996)
We provide a physical basis for the local gravitational superenergy tensor. Furthermore, our gravitoelectromagnetic deduction of the Bel-Debever-Robinson superenergy tensor permits the identification of the gravitational ...
Electronic Structure of the Perovskite Oxides: La1-xCaxMnO3
(American Physical Society, 1996)
The electronic structures of the perovskite oxides, LaMnO3 and CaMnO3, are studied using density-functional methods. Antiferromagnetic insulating (AFI) solutions are obtained for both compounds within the local-density ...
On the spectrum of oscillations of a Schwarzschild black hole
(American Institute of Physics, 1996)
The spectral properties of the resonant oscillations of a Schwarzschild black hole are studied. The analogy with the Coulomb wave equation is developed, and it is shown that the high-overtone quasi-normal modes are intimately ...
Electronic Shell Structure and Relative Abundances of Cesium-Coated C60
(American Physical Society, 1996)
The relative abundances of C60Cs(N), N≤500, determined from mass spectra measurements, are presented and explained in terms of the successive filling of the electronic shells by the cesium valence electrons. The motion of ...
Electron states and electron-phonon coupling in the BEDT-TTF-based organic superconductors
(American Physical Society, 1996)
The electronic structure and the coupling of electrons to the vibrational modes of a single bis (ethylenedithio)-tetrathiafulvalene (BEDT-TTF) molecule, the building block of a class of organic superconductors, are studied ...
Molecular-dynamics simulations of the dynamical excitations in commensurate submonolayer films of nitrogen molecules on graphite
(American Physical Society, 1996)
The dynamics of commensurate submonolayer solids of N2 molecules adsorbed on the basal planes of graphite have been studied using molecular-dynamics simulations. The calculations yielded the temperature dependence of the ...
