Passive Optical Network Approach to GigaHertz-Clocked Multiuser Quantum Key Distribution
Veronica Fernandez, Robert J. Collins, Karen J. Gordon +2
We present the application of quantum key distribution technologies to fiber-based broadband passive optical access networks. This application is based on our 850 nm wavelength gig…
Homogeneous hypersurfaces in complex hyperbolic spaces
Jurgen Berndt, Jose Carlos Diaz-Ramos
We study the geometry of homogeneous hypersurfaces and their focal sets in complex hyperbolic spaces. In particular, we provide a characterization of the focal set in terms of its…
Keck Infrared Observations of GRO J0422+32 in Quiescence
Mark T. Reynolds, Paul J. Callanan, Alexei V. Filippenko
We present Keck K-band photometry and low-resolution H & K-band spectroscopy of the X-ray nova GRO J0422+32 obtained while the system was in the quiescent state. No clear ellipsoid…
Non-uniqueness in conformal formulations of the Einstein constraints
D. M. Walsh
Standard methods in non-linear analysis are used to show that there exists a parabolic branching of solutions of the Lichnerowicz-York equation with an unscaled source. We also app…
Frequency-dependent time delays for strong outbursts in four blazars from the Metsahovi and UMRAO monitoring databases
T. B. Pyatunina, N. A. Kudryavtseva, D. C. Gabuzda +4
The combined data of the University of Michigan Radio Astronomy Observatory and Metsahovi Radio Observatory provide us with radio light curves for Active Galactic Nuclei monitored…
Universal relations on stable map spaces in genus zero
Anca M. Mustata, Andrei Mustata
We introduce a factorization for the map between moduli spaces of stable maps which forgets one marked point. This leads to a study of universal relations in the cohomology of stab…
