Four wave mixing with self-phase matching due to collective atomic recoil
G. R. M. Robb, B. W. J. McNeil
We describe a method for non-degenerate four-wave mixing in a cold sample of 4-level atoms. An integral part of the four-wave mixing process is a collective instability which spont…
Effective magnetic fields in degenerate atomic gases induced by light beams with orbital angular momenta
G. Juzeliunas, P. Ohberg, J. Ruseckas +1
We investigate the influence of two resonant laser beams on the mechanical properties of degenerate atomic gases. The control and probe beams of light are considered to have Orbita…
Results in Optimal Discrimination
Kieran Hunter
We study the problem of discriminating between non-orthogonal quantum states with least probability of error. We demonstrate that this problem can be simplified if we solve for the…
The Semiclassical and Quantum Regimes of Superradiant Light Scattering from a Bose-Einstein Condensate
G. R. M. Robb, N. Piovella, R. Bonifacio
We show that many features of the recent experiments of Schneble et al. [D. Schneble, Y. Torii, M. Boyd, E.W. Streed, D.E. Pritchard and W. Ketterle, Science vol. 300, p. 475 (2003…
Up-dated opacities from the Opacity Project
N. R. Badnell, M. A. Bautista, K. Butler +5
Using the code AUTOSTRUCTURE, extensive calculations of inner-shell atomic data have been made for the chemical elements He, C, N, O, Ne, Na, Mg, Al, Si, S, Ar, Ca, Cr, Mn, Fe and…
A quantum model for collective recoil lasing
R. Bonifacio, M. M. Cola, N. Piovella
Free Electron Laser (FEL) and Collective Atomic Recoil Laser (CARL) are described by the same model of classical equations for properly defined scaled variables. These equations ar…
On the mechanical properties of matter waves
Nicholas K Whitlock, Stephen M Barnett, John Jeffers
Electromagnetic waves and fluids have locally conserved mechanical properties associated with them and we may expect these to exist for matter waves. We present a semiclassical des…
A comparison of Rosseland-mean opacities from OP and OPAL
M. J. Seaton, N. R. Badnell
Monochromatic opacities from the Opacity Project (OP) (Seaton et al.) have been augmented by hitherto missing inner-shell contributions (Badnell & Seaton). OP Rosseland-mean opacit…
Degenerate ground state and anomalous flux hysteresis in an YBa2Cu3O7 grain boundary r.f. SQUID
C. H. Gardiner, R. A. M. Lee, J. C. Gallop +3
We report measurements of the flux hysteresis curves and trapped flux distribution in an YBa2Cu3O7 r.f. SQUID containing two closely spaced grain boundary Josephson junctions in pa…
Vortex sorter for Bose-Einstein condensates
G. Whyte, J. Veitch, P. Ohberg +1
We have designed interferometers that sort Bose-Einstein condensates into their vortex components. The Bose-Einstein condensates in the two arms of the interferometer are rotated w…
Unambiguous comparison of the states of multiple quantum systems
Anthony Chefles, Erika Andersson, Igor Jex
We consider N quantum systems initially prepared in pure states and address the problem of unambiguously comparing them. One may ask whether or not all systems are in the same…
Slow light in degenerate Fermi gases
G. Juzeliunas, P. Ohberg
We investigate the effect of slow light propagating in a degenerate atomic Fermi gas. In particular we use slow light with an orbital angular momentum. We present a microscopic the…
