Question:

a. Let x and px be the coordinate and linear momentum in one dimension. Evaluate the classical Poisson bracket [x, F(px)] classical.

b. Let x and px be the corresponding quantum-mechanical operators this time. Evaluate the commutator [x, exp (ipx α/h)].

c. Using the result obtained in (b), prove that exp (ipx α/h) |x’>, (x | x’> = x’ | x’>) is an Eigen state of the coordinate operator x. What is the corresponding eigenvalue?
