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...
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 ...
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 ...
Tidal acceleration of ultrarelativistic particles
(EDP Sciences, 2005)
We investigate the motion of free relativistic particles relative to the ambient medium around a gravitationally
collapsed system. If the relative speed exceeds a critical value given by c/√2, the gravitational tidal ...
Tidal dynamics in Kerr spacetime
(Institute of Physics, 2006)
The motion of free nearby test particles relative to a stable equatorial circular
geodesic orbit about a Kerr source is investigated. It is shown that the nonlinear
generalized Jacobi equation can be transformed in this ...
Ultrarelativistic motion: inertial and tidal effects in Fermi coordinates
(Institute of Physics, 2004)
Fermi coordinates are the natural generalization of inertial Cartesian
coordinates to accelerated systems and gravitational fields. We study themotion
of ultrarelativistic particles and light rays in Fermi coordinates ...

Astrometric Effects of Secular Aberration
(arXiv, 2005)
One of the main endeavors of fundamental astrometry is to establish a practical realization of an inertial reference frame anchored to celestial objects whose positions are defined in the barycentric coordinates of the ...
Analysis of the center of mass-, rotational- and intramolecular diffusive motions in a monolayer film of intermediate-length alkane molecules adsorbed on a solid surface
(American Institute of Physics, 2004)
The intramolecular diffusive motions associated with the creation and annihilation of gauche defects in intermediate-length alkane molecules adsorbed on a solid surface are relatively slow and on a time scale of nanoseconds. ...
Units of relativistic time scales and associated quantities
(arXiv, 2010)
these quantities should be used with out any adjectives. This suggestion comes from a special discussion forum created within IAU Commission 52 "Relativity in Fundamental Astronomy"....
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 ...
Sub-Microarcsecond Astrometry and New Horizons in Relativistic Gravitational Physics
(arXiv, 2000)
Attaining the limit of sub-microarcsecond optical resolution will completely revolutionize fundamental astrometry by merging it with relativistic gravitational physics. Beyond the sub-microarcsecond threshold, one will meet in the sky a new...
Dynamics of Relativistic Flows
(arXiv, 2004)
Dynamics of relativistic outflows along the rotation axis of a Kerr black hole is investigated using a simple model that takes into account the relativistic tidal force of the central source as well as the Lorentz force ...
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 ...
Kronig-Penney model with the tail-cancellation method
(American Association of Physics Teachers, 2001)
The Kronig-Penney model of an electron moving in a periodic potential is solved by the so-called tail-cancellation method. The problem also serves as a simple illustration of the tail-cancellation method itself.
Nonlocal Transformations for Accelerated Observers
(arXiv, 2009)
According to the locality postulate of special relativity, the measurements of physical fields by accelerated observers at a given event in Minkowski spacetime are related to each other by the representations of the Lorentz group. Nonlocal...
Spin-Gravity Coupling
(arXiv, 2008)
Mathisson's spin-gravity coupling and its Larmor-equivalent interaction, namely, the spin-rotation coupling are discussed. The study of the latter leads to a critical examination of the basic role of locality in relativistic physics. The nonlocal...
Introductory Physics: Writing scheme teaches science to non-scientists
(Institute of Physics, 2007)
Writing-intensive activities can be made use of to implement a 'narrow-but-deep' approach in an undergraduate introductory physics course for non-science majors. In this approach, a carefully selected number of topics are treated not only in more...
