    "abstract": "We investigate the Nth order amplitude squeezing in the fan-state |\\xi\n;2k,f\u003e_F which is a linear superposition of the 2k-quantum nonlinear coherent\nstates. Unlike in usual states where an ellipse is the symbol of squeezing, a\n4k-winged flower results in the fan state. We first derive the analytical\nexpression of squeezing for arbitrary k, N, f and then study in detail the case\nof a laser-driven trapped ion characterized by a specific form of the nonlinear\nfunction f. We show that the lowest order in which squeezing may appear and the\nnumber of directions along which the amplitude may be squeezed depend only on k\nwhereas the precise directions of squeezing are determined also by the other\nphysical parameters involved. Finally, we present a scheme to produce such\nfan-states.",
