Question:
The most general wave function of a particle in the simple harmonic oscillator potential is
Show that the expectation value of position is
where the real constants C and ϕ are given by
Thus the expectation value of position for a particle in the harmonic oscillator oscillates at the classical frequency ω (as you would expect from Ehrenfest’s theorem; see problem 3.19(b)). Use Equation 3.114. As an example, find C and ϕ for the wave function in Problem 2.40.
Problem 3.19(b)
For any (normalized) wave packet representing a particle in the harmonic oscillator potential
Equation 3.114
