Shelving according to the nRules
When a weak photon decay competes with a strong photon decay in a 3-level atom, the weak occasionally prevails over the strong photon. This is the shelving phenomenon. It is assumed in this paper to occur objectively and autonomously, independent of external observation – or lack of observation. We here consider an auxiliary rule-set called the nRules that triggers a non-unitary mechanism that ...
متن کاملOptical Shelving: Suppressed Fluorescence
The shelving phenomenon of quantum optics, originally observed by Dehmelt, is analyzed in terms of the nRules that are given in another paper. The heuristic value of these rules is apparent because they reveal the mechanism that enforces the suppression of fluorescence during the dark period associated with shelving.
متن کاملThe design space of shelving
While using the direct issue mode, dependent instructions cause issue blockages and thus an issue bottleneck. Shelving is a technique to avoid this and to increase the sustained issue rate. It takes advantage of two concepts: (a) the decoupling of dependency checking from instruction issue and (b) significantly widening the instruction window that is scanned in each clock cycle for executable i...
متن کاملNarrow absorption lines induced by electron shelving
We investigate the absorption spectrum of a laser driven V system in which one of the upper levels is metastable. If the Rabi frequency of the laser driving the metastable transition is suuciently small we nd an extremely narrow peak in the stationary absorption spectrum of a weak probe on the strong transition. We give analytical expressions approximating the stationary absorption spectrum. Th...
متن کاملSpectral structures induced by electron shelving.
We investigate the spectrum of resonance uorescence of laser driven three-level systems in the V or connguration where one transition is metastable. If the laser driving the weak transition has a suuciently small Rabi frequency we nd an extremely narrow structure in the resonance uorescence spectrum of the strong transition. Analytical expressions approximating the spectrum are given and the pr...
