#### Unipolar spin diodes and transistors

(American Institute of Physics, 2000-12)

Unipolar devices constructed from ferromagnetic semiconducting materials with variable magnetization direction are shown theoretically to behave very similarly to nonmagnetic bipolar devices such as the p-n diode and the ...

#### Spin-Hall Effect in a [110] GaAs Quantum Well

(American Physical Society, 2006-12)

A self-consistent treatment of the spin-Hall effect requires consideration of the spin- orbit coupling and electron-impurity scattering on equal footing. This is done here for the experimentally relevant case of a [110] ...

#### Announcement of the College of Arts and Science, 1913-1914

(University of Missouri, 1913)

#### The Nature and Origin of Molecular Knots in Planetary Nebulae

(American Institute of Physics, 2005-11)

Planetary Nebulae (PNe) are major contributors to the enrichment of the interstellar medium (ISM). Knots and filaments in the ionized gas images of PNe are common, if not ubiquitous. Additionally, it has been shown that ...

#### Effect of electrical bias on spin transport across a magnetic domain wall

(American Institute of Physics, 2004-09)

We present a theory of the current-voltage characteristics of a magnetic domain wall between two highly spin-polarized materials, which takes into account the effect of the electrical bias on the spin-flip probability of ...

#### The resonance counting function for Schrödinger operators with generic potentials

(2005-05)

We show that the resonance counting function for a Schr¨odinger operator has maximal order of growth for generic sets of real-valued, or
complex-valued, L1-compactly supported potentials.

#### Relativity and Nonlocality

(arXiv, 2000-11)

The basic

**physical**structure of the relativistic theory of gravitation is discussed. The significant role that the Hypothesis of Locality plays in relativity theory is elucidated via the phenomenon of spin-rotation coupling. The limitations...#### Anomalous layering of Fe(CO)5 adsorbed on graphite

(American Physical Society, 1989-02)

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 ...

#### Kronig-Penney model with the tail-cancellation method

(American Association of Physics Teachers, 2001-04)

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.

#### Schrödinger equation for the one-particle density matrix of thermal systems: an alternative formulation of Bose-Einstein condensation

(Institute of Physics, 2007-02)

both with and without the confining trap. The results are in very good agreement with those of the full statistical

**physics**treatment. This is an alternative to the Bose-Einstein condensation in the standard ideal Bose-gas treatment....#### Finite Width and Local Field Corrections to Spin Coulomb Drag in a Quasi-Two-Dimensional Electron Gas

(American Physical Society, 2008-01)

We study the spin Coulomb drag in a quasi-two-dimensional electron gas of finite transverse width, including local field corrections beyond the random phase approximation (RPA). We find that the finite transverse width of ...

#### Modification of the Doppler effect due to the helicity-rotation coupling

(arXiv, 2002-10)

The helicity-rotation coupling and its current empirical basis are examined. The modification of the Doppler effect due to the coupling of photon spin with the rotation of the observer is considered in detail in connection ...

#### On the Speed of Gravity and Relativistic v/c Corrections to the Shapiro Time Delay

(arXiv, 2006-02)

Recent papers by Samuel [1,2] declared that the linearized post-Newtonian v/c effects are too small to have been measured in the recent experiment involving Jupiter and quasar J0842+1845 [3,4,5] that was used to measure ...

#### Gravitomagnetic Accelerators

(arXiv, 2010-05)

We study a simple class of time-dependent rotating Ricci-flat cylindrically symmetric spacetime manifolds whose geodesics admit gravitomagnetic jets. The helical paths of free test particles in these jets up and down ...

#### Acceleration-Induced Nonlocality

(arXiv, 2003-01)

, are pointed out. The

**physical**principles of the nonlocal theory of accelerated observers are presented. The implications of the nonlocal theory are briefly discussed....#### Academic Department : circular of information, 1905-1906

#### An Embedding for General Relativity and its Implications for New **Physics**

(arXiv, 2007-05)

**physical**implications....#### Millimeter Laser Ranging to the Moon: a comprehensive theoretical model for advanced data analysis

(arXiv, 2009-02)

Lunar Laser Ranging (LLR) measurements are crucial for advanced exploration of the evolutionary history of the lunar orbit, the laws of fundamental gravitational

**physics**, selenophysics and geophysics as well as for future human missions to the Moon...#### Gravitational bending of light by planetary multipoles and its measurement with microarcsecond astronomical interferometers

(arXiv, 2007-12)

microarcsecond are taken into account, parametrized, and classified in accordance with their

**physical**origin. We discuss the observational capabilities of the near-future optical and radio interferometers for detecting the Doppler modulation of the radial...#### Beyond the standard IAU framework

(Cambridge university Press, 2010-01)

We discuss three conceivable scenarios of extension and/or modification of the IAU relativistic resolutions on time scales and spatial coordinates beyond the Standard IAU Framework. These scenarios include: (1) the formalism ...
