# Adjusting the Zero Point Energy

As students of quantum mechanics should know, the solution to the quantum harmonic oscillator Hamiltonian gives an elegant result:

$E_n = (n+\frac{1}{2})\hbar\omega$

There's a constant term in the energy when $n$ is zero. This is called the Zero Point Energy.

A student proposes that we get rid of this ridiculous term by simply redefining the Hamiltonian as

$H=\frac{p^2}{2m}+\frac{m\omega^2}{2}x^2-\frac{1}{2}\hbar\omega$

After all, we do this all the time with gravity problems simply by adjusting the reference point.

Is this student successful in removing this offset?
