Eigenfunctions and eigenvalues of the generalized squeeze operator
Chi‐Fai Lo
Abstract
The author has constructed the eigenfunctions and eigenvalue spectrum for the generalized squeeze operator in the Hilbert space of entire functions. Proper eigenstates exist only for beta > mod alpha mod with a discrete eigenvalue spectrum resembling that of a displaced simple harmonic oscillator, whereas for beta < mod alpha mod the generalized squeeze operator has continuum eigenfunctions only.
