Equation (4) is the time-independent Schrödinger equation for the harmonic oscillator. Its solution is shown in all quantum mechanics texts. Bound state solutions exist only when (5) where n is an integer. Each value of En has an associated wavefunction (n = (this is written more simply as ), and some solutions are graphed below. n = 1

Harmonic oscillator states in 1D are usually labeled by the quantum number “n”, with “n=0” being the ground state [since ]. But in this problem, 1s means the ground state and 2p means the component of the first excited state, named in analogy to the hydrogen atom …

The energies (eigenvalues) of the one-dimensional harmonic oscillator may be found from the relations. Combining these, we obtain. Unlike the corresponding classical result, we find that the quantum mechanical energy is quantized, in units of , where ω is the classical frequency ω2 = k/m. v is called the vibrational quantum number.

Hint: recall what the energetic spacing is between any two levels of the harmonic oscillator. Step 4: Find the force constant, k, for the H-H bond. Use the relationship between the force constant and the fundamental frequency. Step 5: Write the wavefunction for the ground state wavefunction of the harmonic oscillator.

Now that we’ve outlined the process for deriving complete wave functions in the presence of a potential, the Quantum Harmonic Oscillator solution is outlined below. For a potential: V x = 1 2 m ω 2 x 2 . We obtain a wave function of the form: Ψ x,t = ∑ mω πℏ 1/4 * 1 2 n *n! * H n mω ℏ x * e -mw x 2 /(2ℏ) *e -i …

3. Simple Harmonic Oscillator. NOTES: We have already discussed the solution of the quantum mechanical simple harmonic oscillator (s.h.o.) in class by direct substitution of the potential energy (3.1) into the one-dimensional, time-independent Schroedinger equation. Recall that C is the spring constant of the spring attached to a mass m .

The quantum harmonic oscillator is the foundation for the understanding of complex modes of vibration also in larger molecules, the motion of atoms in a solid lattice, the theory of heat capacity, etc. ... The time evolution of a state of a quantum harmonic oscillator is then described by a solution of the (time-dependent) Schrödinger equation ...

The linear harmonic oscillator is a model that in fact serves as an approximation to many critical phenomena, though in general not quantum computing (The reason is that the linear harmonic oscillator is linear to all orders in the presence of a driving force. The basic quantum logic device must be highly nonlinear as seen below).
