A CH3CN and HCO+ survey towards southern methanol masers associated with star formation
C. R. Purcell, R. Balasubramanyam, M. G. Burton +32
We present the initial results of a 3-mm spectral line survey towards 83 methanol maser selected massive star-forming regions. Here we report observations of the J=5-4 and 6-5 rota…
An investigation of Fe XV emission lines in solar flare spectra
F P Keenan, K M Aggarwal, D S Bloomfield +2
Previously, large discrepancies have been found between theory and observation for Fe XV emission line ratios in solar flare spectra covering the 224-327 A wavelength range, obtain…
Positronium formation from valence and inner shells in noble gas atoms
L. J. M. Dunlop, G. F. Gribakin
When recent experimental positronium (Ps) formation cross sections in noble gases have been compared with the most up-to date theoretical studies, the agreement is qualitative, but…
Many-body theory of gamma spectra from positron-atom annihilation
L. J. M. Dunlop, G. F. Gribakin
A many-body theory approach to the calculation of gamma spectra of positron annihilation on many-electron atoms is developed. We evaluate the first-order correlation correction to…
Application of the zero-range potential model to positron annihilation on molecules
G. F. Gribakin, C. M. R. Lee
In this paper we use a zero-range potential (ZRP) method to model positron interaction with molecules. This allows us to investigate the effect of molecular vibrations on positron-…
Digital resolution enhancement in surface plasmon microscopy
I. I. Smolyaninov, J. Elliott, G. Wurtz +2
The use of photonic crystal and negative refractive index materials is known to improve resolution of optical microscopy and lithography devices down to 80 nm level. Here we demons…
On the recollision-free excitation of krypton during ultrafast multi-electron tunnel ionization
W A Bryan, S L Stebbings, J McKenna +7
The probability of multiple ionization of krypton by 50 femtosecond circularly polarized laser pulses, independent of the optical focal geometry, has been obtained for the first ti…
Cross-Kerr-based information transfer processes
Jinhyoung Lee, M. Paternostro, C. Ogden +3
The realization of nonclassical states is an important task for many applications of quantum information processing. Usually, properly tailored interactions, different from goal to…
Enhanced dynamical entanglement transfer with multiple qubits
A. Serafini, M. Paternostro, M. S. Kim +1
We present two strategies to enhance the dynamical entanglement transfer from continuous variable (CV) to finite dimensional systems by employing multiple qubits. First, we conside…
B-type supergiants in the SMC: Rotational velocities and implications for evolutionary models
P. L. Dufton, R. S. I. Ryans, S. Simon-Diaz +2
High-resolution spectra for 24 SMC and Galactic B-type supergiants have been analysed to estimate the contributions of both macroturbulence and rotation to the broadening of their…
CaII K observations of QSOs in the line-of-sight to the Magellanic Bridge
J. V. Smoker, F. P. Keenan, H. M. A. Thompson +5
We describe medium-resolution spectroscopic observations taken with the ESO Multi-Mode Instrument in the CaII K line (3933.661 Angstroms) towards 7 QSOs located in the line-of-sigh…
Entanglement of mixed macroscopic superpositions: an entangling-power study
M. Paternostro, H. Jeong, M. S. Kim
We investigate entanglement properties of a recently introduced class of macroscopic quantum superpositions in two-mode mixed states. One of the tools we use in order to infer the…
Generation of a coherent superposition state on demand
M. S. Kim, M. Paternostro
We propose an experimentally feasible scheme to generate a superposition of travelling field coherent states using extremely small Kerr effect and an ancilla which could be a singl…
Results from the Wide Angle Search for Planets Prototype (WASP0) III: Planet Hunting in the Draco Field
Stephen R. Kane, Andrew Collier Cameron, Keith Horne +5
The Wide Angle Search for Planets prototype (WASP0) is a wide-field instrument used to search for extra-solar planets via the transit method. Here we present the results of a monit…
Reconstruction of Atomic Ionization Probabilities in Intense Laser Fields
T. R. J. Goodworth, W. A. Bryan, I. D. Williams +1
Application of a parallel-projection inversion technique to z-scan spectra of multiply charged xenon and krypton ions, obtained by non-resonant field ionization of neutral targets,…
Joint measurements and Bell inequalities
Wonmin Son, Erika Andersson, Stephem M. Barnett +1
Joint quantum measurements of non-commuting observables are possible, if one accepts an increase in the measured variances. A necessary condition for a joint measurement to be poss…
A not so simple local multiplier algebra
Pere Ara, Martin Mathieu
We construct an AF-algebra such that its local multiplier algebra does not agree with , thus answering a question raised…
Classical novae from the POINT-AGAPE microlensing survey of M31 -- II. Rate and statistical characteristics of the nova population
M. J. Darnley, M. F. Bode, E. Kerins +17
We report the results of our statistical study of the POINT-AGAPE CNe catalogue. The first Sloan and analysis of the MMRD relationship in M31 is performed using the resul…
Entanglement reciprocation between qubits and continuous variables
Jinhyoung Lee, M. Paternostro, M. S. Kim +1
We investigate how entanglement can be transferred between qubits and continuous variable (CV) systems. We find that one ebit borne in maximally entangled qubits can be fully trans…
