Singularities of the Magnon Boundstate S-Matrix
Nick Dorey, Keisuke Okamura
We study the conjectured exact S-matrix for the scattering of BPS magnon boundstates in the spin-chain description of planar N=4 SUSY Yang-Mills. The conjectured S-matrix exhibits…
A note on Stein fillings of contact manifolds
Anar Akhmedov, John B. Etnyre, Thomas E. Mark +1
In this note we construct infinitely many distinct simply connected Stein fillings of a certain infinite family of contact 3--manifolds.
A New Superintegrable Hamiltonian
P. E. Verrier, N. W. Evans
We identify a new superintegrable Hamiltonian in 3 degrees of freedom, obtained as a reduction of pure Keplerian motion in 6 dimensions. The new Hamiltonian is a generalization of…
Heavy absorption and soft X-ray emission lines in the XMM-Newton spectrum of the Type 2 radio-loud quasar 3C 234
E. Piconcelli, S. Bianchi, G. Miniutti +4
We report results on a 40 ks XMM-Newton observation of the Type 2 quasar 3C 234. Optical spectropolarimetric data have demonstrated the presence of a hidden broad-line region in th…
The vanishing limit of the square-well fluid: the adhesive hard sphere model as a reference system
J. Largo, M. A. Miller, F. Sciortino
We report a simulation study of the gas-liquid critical point for the square-well potential, for values of well width delta as small as 0.005 times the particle diameter sigma. For…
The Origin and Control of the Sources of AMR in (Ga,Mn)As Devices
A. W. Rushforth, K. Výborný, C. S. King +11
We present details of our experimental and theoretical study of the components of the anisotropic magnetoresistance (AMR) in (Ga,Mn)As. We develop experimental methods to yield dir…
Suzaku observations of Markarian 335: evidence for a distributed reflector
J. Larsson, G. Miniutti, A. C. Fabian +3
We report on a 151 ks net exposure Suzaku observation of the Narrow Line Seyfert 1 galaxy Mrk 335. The 0.5-40 keV spectrum contains a broad Fe line, a strong soft excess below abou…
Different approaches to the second order Klein-Gordon equation
Karim A. Malik, David Seery, Kishore N. Ananda
We derive the Klein--Gordon equation for a single scalar field coupled to gravity at second order in perturbation theory and leading order in slow-roll. This is done in two ways: w…
Geometrodynamical Distances to the Galaxy's Hydrogen Streams
Shoko Jin, Donald Lynden-Bell
We present a geometrodynamical method for determining distances to orbital streams of HI gas in the Galaxy. The method makes use of our offset from the Galactic centre and assumes…
Thermal diffusion and bending kinetics in nematic elastomer cantilever
K. K. Hon, D. Corbett, E. M. Terentjev
Vertically aligned mono-domain nematic liquid crystal elastomers contract when heated. If a temperature gradient is applied across the width of such a cantilever, inhomogeneous str…
Cavity BPM System Tests for the ILC Spectrometer
M. Slater, C. Adolphsen, R. Arnold +18
The main physics programme of the International Linear Collider (ILC) requires a measurement of the beam energy at the interaction point with an accuracy of or better. To…
Implementation of an Optimised Cassegrain System for Radio Telescopes
C. M. Holler, R. E. Hills, M. E. Jones +2
We present the antenna design for a radio interferometer, the Arcminute Microkelvin Imager, together with its beam pattern measurement. Our aim was to develop a low-cost system wit…
Classical capacity of quantum channels with general Markovian correlated noise
Nilanjana Datta, Tony Dorlas
The classical capacity of a quantum channel with arbitrary Markovian correlated noise is evaluated. For the general case of a channel with long-term memory, which corresponds to a…
Infinite-Dimensional Symmetries of Two-Dimensional Coset Models Coupled to Gravity
M. J. Perry, H. Lu, C. N. Pope
In an earlier paper we studied the infinite-dimensional symmetries of symmetric-space sigma models (SSMs) in a flat two-dimensional spacetime. Here, we extend our investigation to…
On the Physical Significance of Infra-red Corrections to Inflationary Observables
N. Bartolo, S. Matarrese, M. Pietroni +2
Inflationary observables, like the power spectrum, computed at one- and higher-order loop level seem to be plagued by large infra-red corrections. In this short note, we point out…
Nanoelectromechanical systems based on multi-walled nanotubes: nanothermometer, nanorelay and nanoactuator
Andrey M. Popov, Yurii E. Lozovik, Elena Bichoutskaia +1
We report on three new types of nanoelectromechanical systems based on carbon nanotubes: an electromechanical nanothermometer, a nanorelay and a nanomotor. The nanothermometer can…
Deformations of Compact Coassociative 4-folds with Boundary
Alexei Kovalev, Jason D. Lotay
Coassociative 4-folds are a particular class of 4-dimensional submanifolds which are defined in a 7-dimensional manifold M with a G_2 structure given by a `positive' differential 3…
The SCUBA Half Degree Extragalactic Survey (SHADES) - IX: the environment, mass and redshift dependence of star formation
S. Serjeant, S. Dye, A. Mortier +17
We present a comparison between the SCUBA Half Degree Extragalactic Survey (SHADES) at 450 and 850 microns in the Lockman Hole East with a deep Spitzer Space Telescope survey at 3.…
Exact reconstruction with directional wavelets on the sphere
Y. Wiaux, J. D. McEwen, P. Vandergheynst +1
A new formalism is derived for the analysis and exact reconstruction of band-limited signals on the sphere with directional wavelets. It represents an evolution of the wavelet form…
Reinstating the 'no-lose' theorem for NMSSM Higgs discovery at the LHC
J. R. Forshaw, J. F. Gunion, L. Hodgkinson +2
The simplest supersymmetric model that solves the mu problem and in which the GUT-scale parameters need not be finely tuned in order to predict the correct value of the Z boson mas…
Cosmic String Dynamics and Evolution in Warped Spacetime
A. Avgoustidis
We study the dynamics and evolution of Nambu-Goto strings in a warped spacetime, where the warp factor is a function of the internal coordinates giving rise to a `throat' region. T…
