Ground state of harmonic oscillator

In summary, the conversation discusses verifying that the ground state wavefunction for a harmonic oscillator is an eigenstate of the Hamiltonian. Using the explicit wavefunction, the average potential and kinetic energies are calculated. The attempt at a solution involves using a standard alteration and obtaining a final equation for the ground state wavefunction.

Homework Statement


Verify that the ground state (n=0) wavefunction is an eigenstate of the harmonic
oscillator Hamiltonian. Using the explicit wavefunction of the ground state to calculate
the average potential energy <0|[tex]\hat{v}[/tex]|0> and average kinetic energy <0|[tex]\hat{T}[/tex]| 0>

You're going to have to make a bit more of an effort to work the problem on your own before you'll get any help here.

ill just go ask this question another website, thanx
 

1. What is the ground state of a harmonic oscillator?

The ground state of a harmonic oscillator is the lowest energy state that the oscillator can occupy. In other words, it is the state with the smallest amount of energy.

2. How is the ground state of a harmonic oscillator determined?

The ground state of a harmonic oscillator can be determined using the Schrödinger equation, which describes the behavior of quantum particles. By solving this equation, we can obtain the wave function of the oscillator and determine its ground state energy.

3. What is the significance of the ground state in a harmonic oscillator?

The ground state is significant because it represents the most stable and lowest energy state of the oscillator. It is the starting point for understanding the behavior and properties of the oscillator in more complex states.

4. Can the ground state of a harmonic oscillator be changed?

The ground state of a harmonic oscillator can be changed if the system is subjected to external forces or interactions. These changes can result in the oscillator occupying a different energy state.

5. How is the ground state of a harmonic oscillator related to the uncertainty principle?

The uncertainty principle states that the position and momentum of a particle cannot be known simultaneously with absolute certainty. In the ground state of a harmonic oscillator, the uncertainty in position and momentum is at its minimum, and this is a consequence of the oscillator being in its lowest energy state.
