Harmonic Oscillator

  1. Apr 19, 2013 #1
    Hi guys,

    is there a reason why the energy of the harmonic oscillator is always written as:$$
    E_{n} = \hbar \omega (n + \frac{1}{2})$$
    instead of :
    E_{n} = h \nu (n + \frac{1}{2})$$

    It means the same, usually QM uses hbar to avoid the 2pi appearing everywhere.
