Impossibility of naively generalizing squeezed coherent states

Pertinent properties of the unitary operators that create coherent states and squeezed coherent states are discussed. We show that certain generalizations of squeezed coherent states do not exist in the Hilbert space of the simple harmonic oscillator, L/sub 2/(SHO). This is accomplished by showing that the generalized squeeze operators exp(z/sub k/(a/sup dagger/)/sup k/+ih/sub k/-1-(z/sub k/)*a/sup k/) are unbounded in L/sub 2/(SHO) for all k>2, where h/sub k/-1 is a Hermitian polynomial in a and a/sup dagger/ up to powers of (k-1).
