Description
We construct generalized coherent states for the one-dimensional double-well potential and calculate their Mandel parameter, uncertainty relation and Wigner functions. The singularities of their autocorrelation function undergo bifurcations as the mean energy of the system is varied, and we analyse their structure. In the high-energy regime these states consist of a coherent superposition of two minimum-uncertainty Gaussians (they are Schroedinger catlike states)
