Variation of the density of states in amorphous GdSi at the metal-insulator transition
(American Physical Society, 2004)
We have performed detailed conductivity and tunneling measurements on the amorphous, magnetically doped material alpha-GdxSi1-x, which can be driven through the metal-insulator transition by the application of an external ...
Physical limits of the ballistic and nonballistic spin-field-effect transistor: Spin dynamics in remote-doped structures
(American Physical Society, 2005)
We investigate the spin dynamics and relaxation in remotely doped two dimensional electron systems where the dopants lead to random fluctuations of the Rashba spin-orbit coupling. Due to the resulting random-spin precession, ...
Superconducting transition temperature in heterogeneous ferromagnet-superconductor systems
(American Physical Society, 2004)
We study the superconducting phase transition in two systems: ferromagnet-superconductor bilayer (FSB) and a thin superconducting film with a periodic array of magnetic dots (SFMD) upon it. We show that this transition is ...
Quasiparticle resonant states induced by a unitary impurity in a d-wave superconductor
(American Physical Society, 2000)
The quasiparticle resonant states around a single nonmagnetic impurity with unitary scattering in a d-wave superconductor is studied by solving the Bogoliubov-de Gennes equations based on a t-J model. Both the spatial ...
Spin glass behavior in FeAl2
(American Physical Society, 2001)
Magnetic and transport measurements indicate FeAl2 to be an ordered intermetallic spin glass, with canonical behavior including a susceptibility cusp at T-f = 35 K and frequency-dependent susceptibility below T-f. The ...
Further test of internal-conversion theory with a measurement in (197)Pt
(American Physical Society, 2009)
We have measured the K-shell internal conversion coefficient, alpha(K), for the 346.5-keV M4 transition in (197)Pt to be 4.23(7). This result differs from a previous value, which disagreed significantly from theory. Our ...
Coupling of electrons to the electromagnetic field in a localized basis
(American Physical Society, 2008)
A simple formula is obtained for coupling electrons in a complex system to the electromagnetic field. It includes the effect of intra-atomic excitations and nuclear motion, and can be applied in, e.g., first-principles-based ...
Charged particle rapidity distributions at relativistic energies
(American Physical Society, 2001)
Using a multiphase transport model (AMPT), which includes both initial partonic and final hadronic interactions, we study the rapidity distributions of charged particles such as protons, antiprotons, pions, and kaons in ...
Analytical and micromagnetic study of a Neel domain wall
(American Physical Society, 2008)
For ferromagnets with exchange, dipolar interaction, and uniaxial anisotropy, by both analytic methods and micromagnetic simulations we study Neel domain walls in thin ferromagnetic strips of finite width. Comparison of ...
Measurements of phi meson production in relativistic heavy-ion collisions at the BNL Relativistic Heavy Ion Collider (RHIC)
(American Physical Society, 2009)
We present results for the measurement of phi meson production via its charged kaon decay channel phi -> K(+) K(-) Au + Au collisions at root S(NN) = 62.4, 130, and 200 GeV, and in p + p and d + Au collisions at v root ...
