Spatiotemporal evolutions of the deformed wavepackets described by the probability density |ψ_{±, 0 0 0}(x,t)|² of Eq. (12) with complicatedly oscillating positions which are described by the time-varying wave-peaks. Hereafter, the blue color and solid curves are associated with sign “+”, the red color and dashed curves correspond to sign “–”, and the right and left wavepackets |〈x|☺〉|² and |〈x|☹〉|² in a plot are always labeled by the live ☺ and dead ☹, respectively. When the packet |ψ_{+, 0 0 0}(x,t)|² is localized on the right or left side, we call the superposition state the kitten state or ill kitten state. All the quantities plotted in the figures of this paper are dimensionless.
