@article{Raffa2019NewQD, title={New quantumness domains through generalized squeezed states}, author={F A Raffa and Mario Rasetti and Marco Genovese}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2019}, volume={52} }

Current definitions of both squeezing operator and squeezed vacuum state are critically examined on the grounds of consistency with the underlying su(1,1) algebraic structure. Accordingly, the generalized coherent states for su(1,1) in its Schwinger two-photon realization are proposed as squeezed states. The physical implication of this assumption is that two additional degrees of freedom become available for the control of quantum optical systems. The resulting physical predictions are…
