%0 Journal Article %T K-quantum nonlinear coherent states: formulation, realization and nonclassical effects %A Nguyen Ba An %J Physics %D 2001 %I arXiv %X We introduce a generalized class of states called K-quantum nonlinear coherent states. Each K-state has K j-components corresponding to one and the same eigenvalue. Each Kj-component can be composed of K K=1-states in a correlated manner. The introduced states are shown to be realized in the long-term behavior of the vibrational motion of an ion properly trapped and laser-driven. Nonclassical properties of the states are studied in detail. %U http://arxiv.org/abs/quant-ph/0103077v2
