Abstract: | In this paper a new class of finite-dimensional even and odd
nonlinear pair coherent states (EONLPCSs), which can be realized via
operating the superposed evolution operators $D_\pm (\tau )$ on the
state $\left| {q,0} \right\rangle $, is constructed, then their
orthonormalized property, completeness relations and some
nonclassical properties are discussed. It is shown that the
finite-dimensional EONLPCSs possess normalization and completeness
relations. Moreover, the finite-dimensional EONLPCSs exhibit
remarkably different sub-Poissonian distributions and phase
probability distributions for different values of parameters $q$,
$\eta $ and $\xi $. |
