NONCLASSICAL EFFECTS OF THE STATES GENERATED BY EXCITATIONS ON A COHERENT STATE OF A HARMONIC OSCILLATOR IN A FINITE-DIMENSIONAL HILBERT SPACE.

The mathematical and physical properties of the states which are generated by excitations on the coherent state of a harmonic oscillator in a finite-dimensional Hilbert space are studied. It is shown that the state exhibits squeezing in one of the quadratures of the field and sub-Poissonian photon statistics. [ABSTRACT FROM AUTHOR]
