Questions and Answers

What is the Hamiltonian operator of the harmonic oscillator in one dimension?

  • Ĥ = p̂2 - mω 2 x̂2 / 2m
  • Ĥ = p̂2 1 + mω 2 x̂2 / 2m (correct)
  • Ĥ = p̂2 - mω 2 x̂2 * 2m
  • Ĥ = p̂2 + mω 2 x̂2 / 2m

    • What does the eigenvalue equation for the harmonic oscillator look like in the {|xi} representation?

  • − ~2 d2ϕ(x)/dx2 + mωxϕ(x) = Eϕ(x) (correct)
  • ~2 d2ϕ(x)/dx2 − mωxϕ(x) = Eϕ(x)
