An informal history of astronomy at the University of Missouri-Columbia
(Dept. of Physics and Astronomy, University of Missouri - Columbia,, 1981)
Neutron interferometry in a rotating frame of reference
(American Physical Society, 1988)
The physical basis for the description of phenomena by a rotating observer is investigated. A simple, yet tentative, extension of the hypothesis of locality is used to determine the interference phase shift induced by the rotation of a neutron...
Center of mass and relative motion in time dependent density functional theory
(American Physical Society, 1995)
It is shown that the theorem asserting separability of the center of mass motion for a system of interacting particles in a harmonic external potential is satisfied in the time dependent density functional theory, provided ...
Rigorous upper bound for the persistent current in systems with toroidal geometry
(American Physical Society, 1995)
It is shown that the absolute value of the persistent current in a system with toroidal geometry is rigorously less than or equal to eħNα/4πmr02, where N is the number of electrons, r0-2= 〈ri-2〉 is the equilibrium average ...
Erratum: Theory of photon bands in three-dimensional periodic dielectric structures
(American Physical Society, 1990)
Erratum correction in reference to Theory of Photon Bands in Three-Dimensional Periodic Dielectric Structures [Phys Rev. Lett. 64 1239 (1990)].
Mashhoon replies
(American Physical Society, 1992)
B. Mashhoon discusses comments made by J. Anandan on the results on the coupling of intrinsic spin to the angular velocity in a neutron interferometry.(AIP)
Generalization of Kerr spacetime
(American Physical Society, 1991)
A class of exact solutions of the Einstein-Maxwell equations is presented. It represents the exterior gravitational field of a charged rotating mass. The class contains a generalization of the charged Kerr metric involving ...
Universal equilibrium currents in the quantum Hall fluid
(American Physical Society, 1995)
The equilibrium current distribution in a quantum Hall fluid that is subjected to a slowly varying confining potential is shown to generally consist of strips or channels of current, which alternate in direction, and which ...
Anomalous layering of Fe(CO)5 adsorbed on graphite
(American Physical Society, 1989)
Synchrotron x-ray diffraction experiments reveal the adsorption of iron pentacarbonyl [Fe(CO)5] on graphite basal-plane surfaces to be an extreme example of incomplete wetting in which only one solid layer of film coexists ...
On the gravitoelectromagnetic stress-energy tensor
(American Institute of Physics, 1999)
We study the pseudo-local gravitoelectromagnetic stress-energy tensor for an arbitrary gravitational field within the framework of general relativity. It is shown that there exists a current of gravitational energy around ...
Gradiometry and gravitomagnetic field detection
(National Aeronautics and Space Administration, Office of Management, Scientific and Technical Information Division, 1989)
Gravitomagnetism was apparently first introduced into physics about 120 years ago when major developments in electrodynamics and the strong similarity between Coulomb's law of electricity and Newton's law of gravity led to the hypothesis that mass...
Bound on the group velocity of an electron in a one-dimensional periodic potential
(American Physical Society, 1995)
By using a recently derived upper bound on the allowed equilibrium current in a ring, it is proved that the magnitude of the group velocity of a Bloch electron in a one- dimensional periodic potential is always less than ...
Refractive index of waterlike fluids
(American Physical Society, 1993)
The refractive index of a waterlike fluid is calculated from a frequency- and wave-vector-dependent dielectric function. This model for the dielectric function of waterlike fluids as symmetric rotors is formulated in terms ...
Center of Mass and Relative Motion in Time Dependent Density Functional Theory
(American Physical Society, 1995)
It is shown that the theorem asserting separability of the center of mass motion for a system of interacting particles in a harmonic external potential is satisfied in the time dependent density functional theory, provided ...
Engineering superfluidity in electron-hole double layers
(American Physical Society, 1998)
We show that band-structure effects are likely to prevent superfluidity in semiconductor electron-hole double-layer systems. We suggest the possibility that superfluidity could be realized by the application of uniaxial ...
Coulomb interaction and persistent currents in ensembles of mesoscopic metal rings
(American Physical Society, 1994)
The average persistent current in an ensemble of mesoscopic metal rings at fixed chemical potential threaded by a magnetic flux in the diffusive regime is related to the presence of a component of the one-electron effective ...
The X-Ray Luminosity Function of Nearby Rich and Poor Clusters of Galaxies:A Cosmological Probe
(American Astronomical Society, 1999)
In this Letter, we present a new determination of the local (z · 0.09) X-ray luminosity function (XLF) using a large, statistical sample of 294 Abell clusters and the ROSAT All-Sky Survey. Despite the optical selection of ...
Edge structure of fractional quantum Hall systems from density-functional theory
(American Physical Society, 1995)
We use the Hohenberg-Kohn formulation of density-functional theory (DFT) to study the density profile at the edge of a confined two-dimensional electron gas in the fractional quantum Hall regime. The strong correlation ...
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 ...
Pressure-induced resonance broadening of exciton line shapes in semiconductors: Direct determination of intervalley scattering rates in GaAs
(American Physical Society, 1991)
We show that the exciton photoluminescence line shape in the GaAs/AlxGa1-xAs quantum wells under pressure is broadened by hybridization of the Γ exciton with the X and the L continua via electron-phonon coupling. Furthermore, ...
