Thermalization of heavy quarks in the quark-gluon plasma
(American Physical Society, 2005)
Charm- and bottom-quark rescattering in a quark-gluon plasma (QGP) is investigated with the objective of assessing the approach toward thermalization. Employing a Fokker-Planck equation to approximate the collision integral ...
Disorder effects in the anomalous Hall effect induced by Berry curvature RID B-5617-2009
(American Physical Society, 2005)
We describe the charge transport in ferromagnets with spin-orbit coupled Bloch bands by combining the wave-packet evolution equations with the classical Bolzmann equation. This approach can be justified in the limit of ...
Nuclear matter symmetry energy and the neutron skin thickness of heavy nuclei RID A-2398-2009
(American Physical Society, 2005)
Correlations between the thickness of the neutron skin in finite nuclei and the nuclear matter symmetry energy are studied in the Skyrme Hartree-Fock model. From the most recent analysis of the isospin diffusion data in ...
Charm elliptic flow in relativistic heavy-ion collisions RID A-2398-2009
(American Physical Society, 2005)
Charm elliptic flow in heavy-ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Assuming that the cross section for charm quark scattering with other light quarks is the same ...
Dissipation and coherent effects in narrow superconducting channels
(American Physical Society, 2005)
We apply the time-dependent Ginzburg-Landau (TDGL) equations to study small ac currents of frequency omega in superconducting channels narrow on the scale of London penetration depth. We show that TDGL equations have ...
Charge Hall effect driven by spin-dependent chemical potential gradients and Onsager relations in mesoscopic systems RID B-8398-2011 RID A-7392-2009
(American Physical Society, 2005)
We study theoretically the spin-Hall effect as well as its reciprocal phenomenon (a transverse charge current driven by a spin-dependent chemical potential gradient) in electron and hole finite size mesoscopic systems. The ...
High precision measurements of Na-26 beta(-) decay
(American Physical Society, 2005)
High-precision measurements of the half-life and beta-branching ratios for the beta(-) decay of Na-26 to Mg-26 have been measured in beta-counting and gamma-decay experiments, respectively. A 4 pi proportional counter and ...
Dependence of the intrinsic spin-Hall effect on spin-orbit interaction character RID B-5617-2009
(American Physical Society, 2005)
We report on a comparative numerical study of the spin-Hall conductivity in two dimensions for three different spin-orbit interaction models
Hadronic modes and quark properties in the quark-gluon plasma
(American Physical Society, 2005)
Based on interaction potentials between a heavy quark and antiquark as extracted from recent QCD lattice calculations, we set up a Brueckner-type many-body scheme to study the properties of light (anti-) quarks in a ...
K(892)(*) resonance production in Au+Au and p+p collisions at root s(NN)=200 GeV
(American Physical Society, 2005)
The short-lived K(892)* resonance provides an efficient tool to probe properties of the hot and dense medium produced in relativistic heavy-ion collisions. We report measurements of K* in root s(NN)=200 GeV Au+Au and p+p ...
