(a) Prove that |A) = e-lAF/2ea" |0) is a normalized consistent state. (b) Test the minimum uncertainty ratio for such a state (c) Write A) as A) = E(n)n). Show that the distribution of If(n)|° is of the type Poisson. Find the most probable value of n, and from here, of E. (d) Show that a consistent state can also be obtained by applying the translation operator et#p/h to the ground state. With the definition of the previous problem, what A corresponds to? Nota: It is suggested to use Cohen's book, volume I, complement GV 9.
