Quantum jumps in atomic systems

摘要: We consider a three-level atomic system driven strongly on one transition and weakly the other. The excited state weak is assumed to be metastable. give an analysis of fluorescence from strong in terms elementary probability density ${p}_{[0}$,t)(${\mathrm{t}}_{1}$,${t}_{2}$,..., ${t}_{n}$) which gives us that exactly n photons are emitted at times ${t}_{1}$,${t}_{2}$,...,${t}_{n}$ by atom time interval [0,t). show ${p}_{[0}$,t) essentially factorizes into products conditional densities c\ifmmode \tilde{}\else \~{}\fi{}(\ensuremath{\tau}) that, given photon zero, next emission occurs \ensuremath{\tau}. This enables simulation individual emissions shows directly existence prolonged dark windows corresponding shelving electron metastable or ``quantum jumps.''
