The two-atom dipole amplitude-squared squeezing in a system of a two-mode vacuum field interacting with two coupled atoms was studied.

Both interactions of a two-level atom with a vacuum field and a excited atom with a coherent field, as examples, are discussed in detail.

This conical beam is then reflected into a cluster of 1m or so rubidium atoms, which are held trapped in a magnetic field within a vacuum chamber.

The atoms in question were stripped of their outer electrons and trapped in an electric field, in a vacuum, at extremely low temperatures.

Mass spectrometry works by evaporating molecules, giving them an electric charge, and then applying an electric field to them and accelerating them through a vacuum chamber to a detector.
