Detecting squeezed boson fields via particle scattering.
01 January 1988
In condensed matter there are many boson fields which, like light, can be driven into a squeezed state through anharmonic interactions with an intense pump. The detection of such squeezed states has been problematic because of the lack of high quantum efficiency detectors. Here a single particle scattering technique is described by which such states can be detected. In particular it is shown that, due to a coherence between a scattering process which involves the emission of a boson and that which involves the absorption of a boson, the scattering rate can be greatly inhibited below that when the boson field is in its vacuum state.
