Dielectric function of diluted magnetic semiconductors in the infrared regime
(American Physical Society, 2004)
We present a study of the dielectric function of metallic (III,Mn)V diluted magnetic semiconductors in the infrared regime. Our theoretical approach is based on the kinetic exchange model for carrier induced (III,Mn)V ...
Manifestation of the spin Hall effect through charge-transport in the mesoscopic regime
(American Physical Society, 2004)
We study theoretically the manifestation of the spin Hall effect in a two-dimensional electronic system with Rashba spin-orbit coupling via dc-transport measurements in realistic mesoscopic H-shape structures. The ...
Magnetization relaxation in (Ga,Mn)As ferromagnetic semiconductors
(American Physical Society, 2004)
We describe a theory of Mn local-moment magnetization relaxation due to p-d kinetic-exchange coupling with the itinerant-spin subsystem in the ferromagnetic semiconductor (Ga,Mn)As alloy. The theoretical Gilbert damping ...
Numerical Solution of Fractional Advection-Dispersion Equation
(2004-05-01)
Numerical schemes and stability criteria are developed for solution of the one-dimensional fractional advection-dispersion equation (FRADE) derived by revising Fick’s first law. Employing 74 sets of dye test data measured ...
Measurement of the polar-angle distribution of leptons from W boson decay as a function of the W transverse momentum in p p ¯ collisions at s = 1.8 TeV
(Physical Review D - Particles, Fields, Gravitation, and Cosmology, 2004)
Cross Sections and Transverse Single-Spin Asymmetries in Forward Neutral-Pion Production from Proton Collisions at s = 200 GeV
(Physical Review Letters, 2004)
Production of e(+)e(-) pairs accompanied by nuclear dissociation in ultraperipheral heavy-ion collisions
(American Physical Society, 2004)
We present data on e(+)e(-) pair production accompanied by nuclear breakup in ultraperipheral gold-gold collisions at a center of mass energy of 200 GeV per nucleon pair. The nuclear breakup requirement selects events at ...
Isoscalar multipole strength in Cd-110 and Cd-116
(American Physical Society, 2004)
The giant resonance region from 10 MeV<E-x<55 MeV in Cd-110 and Cd-116 has been studied with inelastic scattering of 240 MeV alpha particles at small angles including 0degrees. In Cd-110(Cd-116), 88+21-13% (104+23-13%) of ...
Compression mode resonances in Zr-90
(American Physical Society, 2004)
The giant resonance region from 10 MeV < E-x < 55 MeV in Zr-90 has been studied with inelastic scattering of 240 MeV alpha particles at small angles including 0degrees. The isoscalar monopole resonance was found to contain ...
