Completeness and Nonclassicality of Coherent States for Generalized Oscillator Algebras

Figure 9

The blue curve represents the Mandel parameter of the coherent states (34) as a function of . This converges to as . The dashed-red curve represents the Mandel parameter for both the horizontal and vertical signals at the output ports of a beam splitter when it is injected with the state , where is the coherent state (34).
