Numerical methods for non-LTE line radiative transfer: Performance and convergence characteristics
G. -J. van Zadelhoff, C. P. Dullemond, F. F. S. van der Tak +7
Comparison is made between a number of independent computer programs for radiative transfer in molecular rotational lines. The test models are spherically symmetric circumstellar e…
Chemistry as a probe of the structures and evolution of massive star forming regions
S. D. Doty, E. F. van Dishoeck, F. F. S. van der Tak +1
We present detailed thermal and gas-phase chemical models for the envelope of the massive star-forming region AFGL 2591. Time- and space-dependent chemistry are used to study the p…
Contractive projections and operator spaces
Matthew Neal, Bernard Russo
Parallel to the study of finite dimensional Banach spaces, there is a growing interest in the corresponding local theory of operator spaces. We define a family of Hilbertian operat…
Entanglement and perfect quantum error correction
Benjamin Schumacher, Michael D. Westmoreland
The entanglement of formation gives a necessary and sufficient condition for the existence of a perfect quantum error correction procedure.
