energy  eigenstates
  • Assume that Planck’s constant equals 1
  • a harmonic oscillator that vibrates with frequency \(\omega\) can have energy \(\frac{\omega}{2}, (1 +\frac{1}{2})\omega, (2 +\frac{1}{2})\omega,(3 +\frac{1}{2})\omega,\cdots\) in units where
  • The lowest energy is not zero! It’s \(\omega/2\). This is called the ground state energy of the oscillator.
