Generation of even and odd nonlinear coherent states
S Sivakumar · Journal of Physics A Mathematical and General · 2000
We show that a class of even and odd nonlinear coherent states, defined as the eigenstates of the product of a nonlinear function of the number operator and the square of the boson annihilation operator, can be generated in the centre-of-mass motion of a trapped and bichromatically laser-driven ion. The nonclasscial properties of the states are studied.
