Answer (1 of 2): The ground state energy of a quantum harmonic oscillator can be calculated by using non relativistic quantum particle mechanics. Taking the lower limit from the uncertainty principle. Find the energy separation between adjacent quantum states. The uncertainties both get bigger as the energy level goes up, so the ground state represents the smallest value of this product, and it turns out that the ground state of the harmonic oscillator ($$n=0$$) provides the very limit of the uncertainty principle! 2x (a) Use dimensional analysis to estimate the ground state energy and the characteristic size of the ground state wave function in terms of m; h,and !. looks like it could be written as the square of a operator.

Harmonic Oscillator Solution using Operators. In quantum physics, you can use operators to determine the energy eigenstate of a harmonic oscillator in position space. The charm of using the operators a and is that given the ground state, | 0 >, those operators let you find all successive energy states. The energy of the harmonic oscillator is E = p 2 /(2m) + m 2 x 2. The ground state energy is larger than zero. For the harmonic oscillator, having a non-zero ground state energy means that the particle can never sit at the bottom of the potential well.
