Atom Lasers, Coherent States, and Coherence:II. Maximally Robust Ensembles of Pure States
H. M. Wiseman, John A. Vaccaro
As discussed in Wiseman and Vaccaro [quant-ph/9906125], the stationary state of an optical or atom laser far above threshold is a mixture of coherent field states with random phase…
Near Infrared Observations of Galactic Black Hole Candidates
S. Chaty, I. F. Mirabel, P. Goldoni +4
We report on several European Southern Observatory (ESO) near-infrared (NIR) observational campaigns aimed at understanding the nature of galactic black hole candidates. Our result…
The influence of dynamic tides on the apsidal-motion rate in close binaries with an evolved main-sequence star
B. Willems, A. Claret
The validity of the classical formula for the rate of secular apsidal motion in close binaries is investigated for a sequence of models of a 5 solar mass star ranging from the last…
Coherent States from Combinatorial Sequences
Karol A. Penson, Allan I Solomon
We construct coherent states using sequences of combinatorial numbers such as various binomial and trinomial numbers, and Bell and Catalan numbers. We show that these states satisf…
Spectrum of a duality-twisted Ising quantum chain
Uwe Grimm
The Ising quantum chain with a peculiar twisted boundary condition is considered. This boundary condition, first introduced in the framework of the spin-1/2 XXZ Heisenberg quantum…
The Evolving Accretion Disc in the Black Hole X-ray Transient XTE J1859+226
R. I. Hynes, C. A. Haswell, S. Chaty +2
We present HST, RXTE, and UKIRT observations of the broad band spectra of the black hole X-ray transient XTE J1859+226 during the decline from its 1999-2000 outburst. Our UV spectr…
