Mechanisms of positron annihilation on molecules
G. F. Gribakin
The aim of this work is to identify the mechanisms responsible for very large rates and other peculiarities observed in low-energy positron annihilation on molecules. The two mecha…
Dissipation and Vortex Creation in Bose-Einstein Condensed Gases
B. Jackson, J. F. McCann, C. S. Adams
We solve the Gross-Pitaevskii equation to study energy transfer from an oscillating `object' to a trapped Bose-Einstein condensate. Two regimes are found: for object velocities bel…
Quantum interference in the fluorescence of a molecular system
Jin Wang, H. M. Wiseman, Z. Ficek
It has been observed experimentally [H.R. Xia, C.Y. Ye, and S.Y. Zhu, Phys. Rev. Lett. {\bf 77}, 1032 (1996)] that quantum interference between two molecular transitions can lead t…
Modeling the Warm Ionized Interstellar Medium and Its Impact on Elemental Abundance Studies
Kenneth R. Sembach, J. Christopher Howk, Robert S. I. Ryans +1
We present model calculations of ionization fractions for elements in the warm (log T = 4), low-density photoionized interstellar medium (WIM) of the Milky Way. We model the WIM as…
Vortex line and ring dynamics in trapped Bose-Einstein condensates
B. Jackson, J. F. McCann, C. S. Adams
Vortex dynamics in inhomogeneous Bose-Einstein condensates are studied numerically in two and three dimensions. We simulate the precession of a single vortex around the center of a…
Dielectronic Recombination of Ground-State and Metastable Li+ Ions
A. A. Saghiri, J. Linkemann, M. Schmitt +10
Dielectronic recombination has been investigated for Delta-n = 1 resonances of ground-state Li+(1s^2) and for Delta-n = 0 resonances of metastable Li+(1s2s ^3S). The ground-state s…
Vortex structures in dilute quantum fluids
T. Winiecki, J. F. McCann, C. S. Adams
Vortex structures in dilute quantum fluids are studied using the Gross-Pitaevskii equation. The velocity and momentum of multiply quantized vortex rings are determined and their co…
Entanglement Teleportation via Werner States
Jinhyoung Lee, M. S. Kim
Transfer of entanglement and information is studied for quantum teleportation of an unknown entangled state through noisy quantum channels. We find that the quantum entanglement of…
Approximation property of -algebraic Bundles
Ruy Exel, Chi-Keung Ng
In this paper, we will define the reduced cross-sectional -algebras of -algebraic bundles over locally compact groups and show that if a -algebraic bundle has the ap…
Monte Carlo simulation with time step quantification in terms of Langevin dynamics
U. Nowak, R. W. Chantrell, E. C. Kennedy
For the description of thermally activated dynamics in systems of classical magnetic moments numerical methods are desirable. We consider a simple model for isolated magnetic parti…
Exact Quantum Solutions of Extraordinary N-body Problems
D. Lynden-Bell, R. M. Lynden-Bell
The wave functions of Boson and Fermion gases are known even when the particles have harmonic interactions. Here we generalise these results by solving exactly the N-body Schroding…
A Characterization of Compact-friendly Multiplication Operators
Y. A. Abramovich, C. D. Aliprantis, O. Burkinshaw +1
Answering in the affirmative a question posed in [Y.A.Abramovich, C.D.Aliprantis and O.Burkinshaw, Multiplication and compact-friendly operators, Positivity 1 (1997), 171--180], we…
Field dependence of the temperature at the peak of the ZFC magnetization
H. Kachkachi, W. T. Coffey, D. S. F. Crothers +4
The effect of an applied magnetic field on the temperature at the maximum of the ZFC magnetization, , is studied using the recently obtained analytic results of Coffey et…
Thermally activated escape rates of uniaxial spin systems with transverse field
D. A. Garanin, E. C. Kennedy, D. S. F. Crothers +1
Classical escape rates of uniaxial spin systems are characterized by a prefactor differing from and much smaller than that of the particle problem, since the maximum of the spin en…
