Microscopic model for the magnetic subsystem in HoNi2B2C
(American Physical Society, 1998)
We demonstrate that the system of localized magnetic moments in HoNi2B2C can be described by the four-positional clock model. This model, at a proper choice of the coupling constants, yields several metamagnetic phases in ...
Hybrid skew scattering regime of the anomalous Hall effect in Rashba systems: Unifying Keldysh, Boltzmann, and Kubo formalisms RID B-3617-2008
(American Physical Society, 2008)
We present the analytical description of the anomalous Hall effect (AHE) in a two-dimensional electron gas (2DEG) ferromagnet within the Keldysh formalism. These results unify the three linear-response approaches to AHE ...
Impurity-induced configuration-transition in the Fulde-Ferrell-Larkin-Ovchinnikov state of a d-wave superconductor
(American Physical Society, 2007)
The effect of impurities on Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states in a layered superconductor with d-wave pairing symmetry is investigated using the tight-binding model and the Bogoliubov-de Gennes equations. At ...
Screening and Tunneling at Metal-Surfaces

Si(100) Surface-States - a Success for the (2x1) Asymmetric Dimer Model
(American Physical Society, 1982)
Kaon dispersion relation and flow in relativistic heavy-ion collisions
(American Physical Society, 1996)
Within the framework of a relativistic transport model (ART) for heavy-ion collisions at AGS energies, we examine the effects of a kaon dispersion relation on the transverse flow of kaons and their transverse momentum and ...
Beta-Gamma-Angular Correlation in Na-20
(American Physical Society, 1981)
Relative Sizes of Ca-40,48 from Scattering of 79 Mev Alpha-Particles

Pentaquark Theta(+) production from the reaction gamma p ->pi K-+(-)Theta(+)
(American Physical Society, 2004)
The cross section for theta(+) production from the reaction gammap-->pi(+)K(-)theta(+), which was observed in the CLAS experiment at the Jefferson National Laboratory, is evaluated in a hadronic model that includes couplings ...
Quantum search protocol for an atomic array
(American Physical Society, 2001)
Quantum computers can, in principle, exceed the speed of ordinary computers by taking advantage of quantum coherence and entanglement. It is possible to find a "needle in a haystack" of N-1 straws in only rootN searches ...
