Bohmian Histories and Decoherent Histories
The predictions of the Bohmian and the decoherent (or consistent) histories formulations of the quantum mechanics of a closed system are compared for histories — sequences of alternatives at a series of times. For certain kinds of histories, Bohmian mechanics and decoherent histories may both be formulated in the same mathematical framework within which they can be compared. In that framework, ...
متن کاملStrengths and weaknesses of a synchronisation: possible jumps to other climate histories paced by the astronomical forcing
Paleoclimatic records have shown evidence of glacial/interglacial asymmetric cycles over the last millions years of the Plio/Pleistocene. In Milankovitch’s theory, these ice ages may be related to the incoming solar radiation (insolation), induced by a varying Sun-Earth astronomical configuration. This astronomical forcing is often said to be a ‘pacemaker’ of ice ages (Hays et al. 1976); the un...

متن کاملThe Virtual Astronomical Observatory: Re-engineering access to astronomical data
TheUSVirtual Astronomical Observatorywas a software infrastructure anddevelopment project designed both to begin the establishment of an operational Virtual Observatory (VO) and to provide the US coordination with the international VO effort. The concept of the VO is to provide the means by which an astronomer is able to discover, access, and process data seamlessly, regardless of its physical ...
متن کاملIntegrated optics for astronomical interferometry - I. Concept and astronomical applications
We propose a new instrumental concept for long-baseline optical single-mode interferometry using integrated optics which were developed for telecommunication. Visible and infrared multi-aperture interferometry requires many optical functions (spatial filtering, beam combination, photometric calibration, polarization control) to detect astronomical signals at very high angular resolution. Since ...
