Query: Spectrum-Generating Superalgebra for Linear Harmonic Oscillators   We show that the Hilbert space of the standard linear harmonic oscillator is
a complete orbit of the osp(2,1;2) spectrum-generating superalgebra, and that
this is the smallest such algebraic structure. The ubiquitous appearance of the
linear harmonic oscillator in virtually all domains of theoretical physics
guarantees a corresponding ubiquity of appropriate generalizations of this
spectrum-generating superalgebra.
