Analysis of the quantum numbers JPC of the X(3872) particle
(2007)We present an analysis of angular distributions and correlations of the X(3872) particle in the exclusive decay mode X(3872)→J/ψπ+π- with J/ψ→μ+μ-. We use 780pb-1 of data from pp̄ collisions at s=1.96TeV collected with the ...

Competing broken-symmetry and rotationally symmetric spin-singlet states in a few-electron quantum dot in a magnetic field
(2008)On the basis of developed variational many-body approach, within a second quantized formulation, the nature of the ground state of a few-electron system in a parabolic two-dimensional (2D) quantum dot (QD) is theoretically ...

Diol-type ligands as central 'players' in the chemistry of high-spin molecules and single-molecule magnets
(2008)The combination of diol-type ligands with paramagnetic transition metal ions has led to the isolation of a host of new homometallic and heterometallic clusters, high-spin molecules and single molecule magnets ranging in ...

Electrical determination of the spin relaxation time of photoexcited electrons in GaAs
(2010)Spin-dependent transport for photoexcited electrons in an epitaxial Fe/GaAs interface was characterized from 5 to 300 K. The presence of spin-dependent transport was confirmed at all the measured temperatures and the spin ...

Numerical calculation model for spin-dependent transport of photoexcited electrons across Fe/GaAs(0 0 1) interfaces
(2010)abs Spin-dependent transport of photogenerated electrons across Fe/GaAs(0 0 1) interfaces is calculated using a one-dimensional electron transport model. Creation of spin-polarized electrons by photoexcitation in this model ...
