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.

9.1 Two identical, non-interacting spin-1/2 particles of mass m are in the one-dimensional harmonic oscillator for which the Hamiltonian is. a) Determine the ground state and first excited state kets and corresponding energies when the two particles are in a total spin-0 state. What are the lowest energy states and corresponding kets for the particles if they are in a total spin-1 state?

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 .

A simple harmonic oscillator is simply an oscillator that is neither damped nor driven. So the equation to describe one is: Physically, the above never actually exists, since there will always be friction or some other resistance, but two approximate examples are a mass on a spring and an LC circuit.
