Abstract: | Using a numerical computational method, quasiprobability distributions
of new kinds of even and odd nonlinear coherent states (EONLCS) are
investigated. The results show that the distributions of the new
even nonlinear coherent states (NLCS) are distinct from those of the new
odd NLCS and imply that the new EONLCS always exhibit some different
nonclassical effects. Finally, with the aid of newly introduced
intermediate coordinate-momentum representation in quantum optics,
the tomograms of the new EONLCS are calculated. This is a new way of
obtaining the tomogram function. |
