Squeezing via superpositions of even and odd Sp(2,R) coherent states
H. A. Schmitt, A. Mufti · Physical Review A · 1991
It is shown that a linear combination of ``even'' and ``odd'' Sp(2,R) coherent states can be more highly squeezed than a coherent state belonging to a single Sp(2,R) representation. Physical mechanisms for generating such superpositions are introduced and studied.
