We use sensitive observations of three high redshift sources; [CII] fine structure and CO(2-1) rotational transitions for the z=6.4 Quasar host galaxy (QSO) J1148+5251, and [CII] and CO(5-4) transitions from the QSO BR1202-0725 and its sub-millimeter

Quantum Arrival and Dwell Times via Idealised Clocks

Autor: Yearsley, J. M., Downs, D. A., Halliwell, J. J., Hashagen, A. K.

Publikováno v: Phys. Rev. A 84, 022109 (2011)

A number of approaches to the problem of defining arrival and dwell time probabilities in quantum theory make use of idealised models of clocks. An interesting question is the extent to which the probabilities obtained in this way are related to stan
