Abstract
A two-mode photon operator satisfying the canonical boson commutation relations is used to define two-mode coherent states for the Weyl, SU(2) and SU(1,1) groups. In all these cases squeezing is determined by an appropriate correlation, which the authors evaluate. The generalisation to multi-mode, many-photon states is indicated.Keywords
