A versatile and reliably re-usable ultrahigh vacuum viewport
K. J. Weatherill, J. D. Pritchard, C. S. Adams +3
We present a viewport for use in Ultra-high vacuum (UHV) based upon the preflattened solder seal design presented in earlier work, Cox et al. Rev. Sci. Inst. 74, 3185 (2003). The d…
Entropic uncertainties for joint quantum measurements
Thomas Brougham, Erika Andersson, Stephen M Barnett
We investigate the uncertainty associated with a joint quantum measurement of two components of spin of a spin-1/2 particle and quantify this in terms of entropy. We consider two e…
Momentum exchange between light and a single atom: Abraham or Minkowski?
E. A. Hinds, Stephen M. Barnett
We consider the forces exerted by a pulse of plane-wave light on a single atom. The leading edge of the pulse exerts a dispersive force on the atom, and this modifies the atomic mo…
On the use of stabilising transformations for detecting unstable periodic orbits in the Kuramoto-Sivashinsky equation
Jonathan J. Crofts, Ruslan L. Davidchack
In this paper we develop further a method for detecting unstable periodic orbits (UPOs) by stabilising transformations, where the strategy is to transform the system of interest in…
R-matrix inner-shell electron-impact excitation of Fe including Auger-plus-radiation damping
G Y Liang, A D Whiteford, N R Badnell
We present results for the inner-shell electron-impact excitation of Fe using the intermediate-coupling frame transformation {\it R}-matrix approach in which Auger-plus-rad…
Upper bounds on fault tolerance thresholds of noisy Clifford-based quantum computers
M. B. Plenio, S. Virmani
We consider the possibility of adding noise to a quantum circuit to make it efficiently simulatable classically. In previous works this approach has been used to derive upper bound…
A Quantum Fluid Description of the Free Electron Laser
R. Bonifacio, N. Piovella, G. R. M Robb +1
Using the Madelung transformation we show that in a quantum Free Electron Laser (QFEL) the beam obeys the equations of a quantum fluid in which the potential is the classical poten…
Quantum state discrimination
Stephen M. Barnett, Sarah Croke
It is a fundamental consequence of the superposition principle for quantum states that there must exist non-orthogonal states, that is states that, although different, have a non-z…
On the conditions for discrimination between quantum states with minimum error
Stephen M. Barnett, Sarah Croke
We provide a simple proof for the necessity of conditions for discriminating with minimum error between a known set of quantum states.
Passage-time moments and hybrid zones for the exclusion-voter model
Iain M. MacPhee, Mikhail V. Menshikov, Stanislav Volkov +1
We study the non-equilibrium dynamics of a one-dimensional interacting particle system that is a mixture of the voter model and the exclusion process. With the process started from…
All-sky LIGO Search for Periodic Gravitational Waves in the Early S5 Data
LIGO Scientific Collaboration
We report on an all-sky search with the LIGO detectors for periodic gravitational waves in the frequency range 50--1100 Hz and with the frequency's time derivative in the range -5.…
Aligning VLBI Images of Active Galactic Nuclei at Different Frequencies
S. M. Croke, D. C. Gabuzda
Many important techniques for investigating the properties of extragalactic radio sources, such as spectral-index and rotation-measure mapping, involve the comparison of images at…
Search for Gravitational Wave Bursts from Soft Gamma Repeaters
LIGO Scientific Collaboration, S. Barthelmy, N. Gehrels +2
We present the results of a LIGO search for short-duration gravitational waves (GWs) associated with Soft Gamma Repeater (SGR) bursts. This is the first search sensitive to neutron…
3D Electron Fluid Turbulence at Nanoscales in Dense Plasmas
Dastgeer Shaikh, P. K. Shukla
We have performed three dimensional nonlinear fluid simulations of electron fluid turbulence at nanoscales in an unmagnetized warm dense plasma in which mode coupling between wave…
First joint search for gravitational-wave bursts in LIGO and GEO600 data
LIGO Scientific Collaboration, B. Abbott
We present the results of the first joint search for gravitational-wave bursts by the LIGO and GEO600 detectors. We search for bursts with characteristic central frequencies in the…
Dark dynamic acousto-optic ring lattices for ultracold atoms
N. Houston, E. Riis, A. S. Arnold
We demonstrate the optical generation of dynamic dark optical ring lattices, which do not require Laguerre-Gauss beams, large optical coherence lengths or interferometric stability…
Periodic and Solitary Travelling-Wave Solutions of an Extended Reduced Ostrovsky Equation
E. John Parkes
Periodic and solitary travelling-wave solutions of an extended reduced Ostrovsky equation are investigated. Attention is restricted to solutions that, for the appropriate choice of…
Moments of exit times from wedges for non-homogeneous random walks with asymptotically zero drifts
Iain M. MacPhee, Mikhail V. Menshikov, Andrew R. Wade
We study quantitative asymptotics of planar random walks that are spatially non-homogeneous but whose mean drifts have some regularity. Specifically, we study the first exit time $…
Short wavelength regenerative amplifier free electron lasers
D. J. Dunning, B. W. J. McNeil, N. R. Thompson
In this paper we discuss extending the operating wavelength range of tunable Regenerative Amplifier FELs to shorter wavelengths than current design proposals, notably into the XUV…
Beating the spin-down limit on gravitational wave emission from the Crab pulsar
The LIGO Scientific Collaboration, B. Abbott, R. Abbott +440
We present direct upper limits on gravitational wave emission from the Crab pulsar using data from the first nine months of the fifth science run of the Laser Interferometer Gravit…
The Einstein@Home search for periodic gravitational waves in LIGO S4 data
LIGO Scientific Collaboration, B. Abbott
A search for periodic gravitational waves, from sources such as isolated rapidly-spinning neutron stars, was carried out using 510 hours of data from the fourth LIGO science run (S…
Electron density diagnostic for hot plasmas in coronal regime by using B-like ions
Guiyun Liang, Gang Zhao
Line ratio of transition lines in boron-like spectra of Si X, S XII, Ar XIV and Fe XXII has been investigated. Collisional-radiative model calculations reveal that the line…
A Smooth, Inductively Coupled Ring Trap for Atoms
P. F. Griffin, E. Riis, A. S. Arnold
We propose and numerically investigate a scalable ring trap for cold atoms that surmounts problems of roughness of the potential and end--effects of trap wires. A stable trapping p…
Astrophysically Triggered Searches for Gravitational Waves: Status and Prospects
The LIGO Scientific Collaboration, Virgo Collaboration
In gravitational-wave detection, special emphasis is put onto searches that focus on cosmic events detected by other types of astrophysical observatories. The astrophysical trigger…
