Surface acoustic wave induced magnetoresistance oscillations in a 2D electron gas
John P. Robinson, Malcolm P. Kennett, Nigel R. Cooper +1
We study the geometrical commensurability oscillations imposed onto the resistivity of 2D electrons in a perpendicular magnetic field by a propagating surface acoustic wave (SAW).…
Structural and electrical properties of c-axis oriented Y1-xCaxBa2(Cu1-yZny)3O7-delta thin films grown by pulsed laser deposition
S. H. Naqib, R. A. Chakalov, J. R. Cooper
Ca- and Zn-subsituted Y1-xCaxBa2(Cu1-yZny)O7-delta (x = 0, 0.05 and y = 0, 0.02, 0.04, 0.05) thin films were grown on SrTiO3 (100) substrates using the pulsed laser deposition (PLD…
Non-Abelian pp-waves in D=4 supergravity theories
M. Cariglia, G. W. Gibbons, R. Guven +1
The non-Abelian plane waves, first found in flat spacetime by Coleman and subsequently generalized to give pp-waves in Einstein-Yang-Mills theory, are shown to be 1/2 supersymmetri…
Representations of G+++ and the role of space-time
A. Kleinschmidt, P. West
We consider the decomposition of the adjoint and fundamental representations of very extended Kac-Moody algebras G+++ with respect to their regular A type subalgebra which, in the…
Radiative transfer through the Intergalactic Medium
James Bolton, Avery Meiksin, Martin White
We use a probabilistic method to compute the propagation of an ionization front corresponding to the re-ionization of the intergalactic medium in a LCDM cosmology, including both h…
CIV Absorbers in z>4 Quasars: Tracing Early Galactic Halos Evolution
Celine Peroux, Patrick Petitjean, Bastien Aracil +2
We use 29 z>4 quasar spectra to build a homogeneous sample of high-redshift CIV absorbers. We use these data to calculate the number density, n(z), of W_rest(CIV)>0.30 A CIV double…
Angular Momentum Transport by MHD Turbulence in Accretion Disks: Gas Pressure Dependence of the Saturation Level of the Magnetorotational Instability
Takayoshi Sano, Shu-ichiro Inutsuka, Neal J. Turner +1
The saturation level of the magnetorotational instability (MRI) is investigated using three-dimensional MHD simulations. The shearing box approximation is adopted and the vertical…
A probabilistic and information theoretic interpretation of quantum evolutions
J. Oppenheim, B. Reznik
In quantum mechanics, outcomes of measurements on a state have a probabilistic interpretation while the evolution of the state is treated deterministically. Here we show that one c…
W Boson Polarisation at LEP2
The OPAL collaboration, G. Abbiendi
Elements of the spin density matrix for W bosons in e+e- -> W+W- -> qqln events are measured from data recorded by the OPAL detector at LEP. This information is used calculate pola…
Magnetic polarons and magnetoresistance in EuB6
M. J. Calderon, L. G. L. Wegener, P. B. Littlewood
EuB6 is a low carrier density ferromagnet which exhibits large magnetoresistance, positive or negative depending on temperature. The formation of magnetic polarons just above the m…
Regularization of the linearized gravitational self-force for branes
R. A. Battye, B. Carter, A. Mennim
We discuss the linearized, gravitational self-interaction of a brane of arbitrary codimension in a spacetime of arbitrary dimension. We find that in the codimension two case the gr…
Membrane solitons in eight-dimensional hyper-Kaehler backgrounds
Ruben Portugues
We derive the BPS equations satisfied by lump solitons in -dimensional sigma models with toric 8-dimensional hyper-Kähler () target spaces and check they preserve 1/…
Measurement of the partial widths of the Z into up- and down-type quarks
The OPAL collaboration, G. Abbiendi
Using the entire OPAL LEP1 on-peak Z hadronic decay sample, Z -> qbarq gamma decays were selected by tagging hadronic final states with isolated photon candidates in the electromag…
Flavour independent search for Higgs bosons decaying into hadronic final states in e+e- collisions
The OPAL collaboration, G. Abbiendi
A search for the Higgsstrahlung process e+e- -> hZ is described, where the neutral Higgs boson h is assumed to decay into hadronic final states. In order to be sensitive to a broad…
Stress in planar cellular solids and isostatic granular assemblies: Coarse-graining the constitutive equation
Raphael Blumenfeld
A recent theory for stress transmission in isostatic granular and cellular systems predicts a constitutive equation that couples the stress field to the local microstructure. The t…
Linear polarization on Gamma-Ray Bursts: from the prompt to the late afterglow
Davide Lazzati
The past year has witnessed a large increase in our knowledge of the polarization properties of Gamma-Ray Burst (GRB) radiation. In the prompt phase, the measurement (albeit highly…
Quantized charge pumping through a quantum dot by surface acoustic waves
J. Ebbecke, N. E. Fletcher, T. J. B. M. Janssen +4
We present a realization of quantized charge pumping. A lateral quantum dot is defined by metallic split gates in a GaAs/AlGaAs heterostructure. A surface acoustic wave whose wavel…
IZw1 observed with XMM-Newton: Low-energy spectral complexity, iron lines, and hard X-ray flares
L. C. Gallo, Th. Boller, W. N. Brandt +2
We present a 20 ks XMM-Newton observation of the prototypical Narrow-Line Seyfert 1 galaxy IZw1. The best-fit model to the data is a double blackbody plus a dominant power-law, on…
Realistic D-Brane Models on Warped Throats: Fluxes, Hierarchies and Moduli Stabilization
J. F. G. Cascales, M. P. Garcia del Moral, F. Quevedo +1
We describe the construction of string theory models with semirealistic spectrum in a sector of (anti) D3-branes located at an orbifold singularity at the bottom of a highly warped…
