摘要

A D =1 position-dependent mass approach to constructing nonlinear quantum states for a modified Coulomb potential is used to generate Gazeau-Klauder coherent states.It appears that their energy eigenvalues are scaled down by the quantum number and the nonlinearity coefficient.We study the basic properties of these states,which are found to be undefined on the whole complex plane,and some details of their revival structure are discussed.
