Adaptable-radius, time-orbiting magnetic ring trap for Bose-Einstein condensates
A S Arnold
We theoretically investigate an adjustable-radius magnetic storage ring for laser-cooled and Bose-condensed atoms. Additionally, we discuss a novel time-dependent variant of this a…
Collective Atomic Recoil Lasing Including Friction and Diffusion Effects
G. R. M. Robb, N. Piovella, A. Ferraro +3
We extend the Collective Atomic Recoil Lasing (CARL) model including the effects of friction and diffusion forces acting on the atoms due to the presence of optical molasses fields…
Transverse laser modes in Bose-Einstein condensates
G. Whyte, P. Ohberg, J. Courtial
We examine the Bose-Einstein-condensate (BEC) equivalent of transverse aspects of laser resonators. We model numerically repeated focussing of a 2-dimensional BEC, which could be a…
Multiplicity of periodic solutions in bistable equations
Gregory Berkolaiko, Michael Grinfeld
We study the number of periodic solutions in two first order non-autonomous differential equations both of which have been used to describe, among other things, the mean magnetizat…
Atomic interaction effects in the superradiant light scattering from a Bose-Einstein condensate
N. Piovella, L. Salasnich, R. Bonifacio +1
We investigate the effects of the atomic interaction in the Superradiant Rayleigh scattering from a Bose-Einstein condensate driven by a far-detuned laser beam. We show that for a…
Node-node distance distribution for growing networks
K. Malarz, J. Karpinska, A. Kardas +1
We present the simulation of the time evolution of the distance matrix. The result is the node-node distance distribution for various kinds of networks. For the exponential trees,…
On the importance of inner-shell transitions for opacity calculations
N. R. Badnell, M. J. Seaton
For high temperatures and densities, stellar opacities obtained from the Opacity Project (OP) were smaller than those obtained from the OPAL project. Iglesias and Rogers [Ap.J. v44…
No quantum ergodicity for star graphs
G. Berkolaiko, J. P. Keating, B. Winn
We investigate statistical properties of the eigenfunctions of the Schrodinger operator on families of star graphs with incommensurate bond lengths. We show that these eigenfunctio…
Semiclassical theory of matter-wave detection
Nicholas K. Whitlock, Stephen M. Barnett, John Jeffers
We derive a semiclassical theory for the detection of matter-waves. This theory draws on the theories of semiclassical optical detection and fluid mechanics. We observe that the in…
Relative phase fluctuations of two coupled one-dimensional condensates
Nicholas Whitlock, Isabelle Bouchoule
We study the relative phase fluctuations of two one-dimensional condensates coupled along their whole extension with a local single-atom interaction. The thermal equilibrium is def…
Comparing the states of many quantum systems
Igor Jex, Erika Andersson, Anthony Chefles
We investigate how to determine whether the states of a set of quantum systems are identical or not. This paper treats both error-free comparison, and comparison where errors in th…
Violation of self-similarity in the expansion of a 1D Bose gas
P. Pedri, L. Santos, P. Ohberg +1
The expansion of a 1D Bose gas is investigated employing the Lieb-Liniger equation of state within the local density approximation. We show that during the expansion the density pr…
Dielectronic recombination data for dynamic finite-density plasmas I. Goals and methodology
N. R. Badnell, M. G. O'Mullane, H. P. Summers +7
A programme is outlined for the assembly of a comprehensive dielectronic recombination database within the generalized collisional--radiative (GCR) framework. It is valid for model…
Assessment of the Fluorescence and Auger Data Base used in Plasma Modeling
T. W. Gorczyca, C. N. Kodituwakku, K. T. Korista +5
We have investigated the accuracy of the 1s-vacancy fluorescence data base of Kaastra & Mewe (1993, A&AS, 97, 443) resulting from the initial atomic physics calculations and the su…
Experimental demonstration of quantum source coding
Y. Mitsumori, J. A. Vaccaro, S. M. Barnett +4
We report an experimental demonstration of Schumacher's quantum noiseless coding theorem. Our experiment employs a sequence of single photons each of which represents three qubits.…
Intermediate wave-function statistics
G. Berkolaiko, J. P. Keating, B. Winn
We calculate statistical properties of the eigenfunctions of two quantum systems that exhibit intermediate spectral statistics: star graphs and Seba billiards. First, we show that…
Retrodictive states and two-photon quantum imaging
E. -K. Tan, John Jeffers, Stephen M. Barnett +1
We use retrodictive quantum theory to analyse two-photon quantum imaging systems. The formalism is particularly suitable for calculating conditional probability distributions.
