Precise determination of low-Q nucleon electromagnetic form factors and their impact on parity-violating e-p elastic scattering
John Arrington, Ingo Sick
The extraction of the strangeness form factors from parity violating elastic electron-proton scattering is sensitive to the electromagnetic form factors at low Q^2. We provide para…

Charles T. Liu, Eric J. Hooper, Karen O'Neil +3
We present multiwavelength observations of the very luminous "E+A" galaxy known as G515 (J152426.55+080906.7), including deep K_s imaging, spatially resolved H-alpha spectroscopy,…
Generation of Spin Entanglement in Nonequilibrium Quantum Dots
Stefan Legel, Jürgen König, Guido Burkard +1
We propose schemes for generating spatially-separated spin entanglement in systems of two quantum dots with onsite Coulomb repulsion weakly coupled to a joint electron reservoir. A…
Interplay of electromagnetic noise and Kondo effect in quantum dots
Serge Florens, Pascal Simon, Sabine Andergassen +1
We investigate the influence of an electromagnetic environment, characterized by a finite impedance , on the Kondo effect in quantum dots. The circuit voltage fluctuations co…
Low complexity method for large-scale self-consistent ab initio electronic-structure calculations without localization
M. J. Rayson
A novel low complexity method to perform self-consistent electronic-structure calculations using the Kohn-Sham formalism of density functional theory is presented. Localization con…
Estimation of Galactic model parameters with the SDSS and metallicity distribution in two fields in the anti-centre direction of the Galaxy

We estimated the Galactic model parameters from the SDSS data reduced for two fields in the anti-centre direction of the Galaxy, , and symmetric relative to the Galacti…
Nuclear spin ferromagnetic phase transition in an interacting 2D electron gas
Pascal Simon, Daniel Loss
Electrons in a two-dimensional semiconducting heterostructure interact with nuclear spins via the hyperfine interaction. Using a a Kondo lattice formulation of the electron-nuclear…
Stellar kinematics and metallicities in the Leo I dwarf spheroidal galaxy -- wide field implications for galactic evolution
A. Koch, M. I. Wilkinson, J. T. Kleyna +5
We present low-resolution spectroscopy of 120 red giants in the Galactic satellite dwarf spheroidal (dSph) Leo I, obtained with the GeminiN-GMOS and Keck-DEIMOS spectrographs. We f…
Medium resolution spectroscopy in Omega Centauri: abundances of 400 subgiant and turn-off region
Andrea Kayser, Michael Hilker, Tom Richtler +1
Medium resolution spectra of more than 400 subgiant and turn-off region stars in Omega Centauri were analysed. The observations were performed at the VLT/Paranal with FORS2/MXU. In…
Fluctuations and topological transitions of quantum Hall stripes: nematics as anisotropic hexatics
A. M. Ettouhami, C. B. Doiron, R. Côté
We study fluctuations and topological melting transitions of quantum Hall stripes near half-filling of intermediate Landau levels. Taking the stripe state to be an anisotropic Wign…
Spin qubits in graphene quantum dots
B. Trauzettel, Denis V. Bulaev, Daniel Loss +1
We propose how to form spin qubits in graphene. A crucial requirement to achieve this goal is to find quantum dot states where the usual valley degeneracy in bulk graphene is lifte…
