What is the Eigenvalue Equation for a 2D Harmonic Oscillator?

In summary, the conversation is about solving for the energy of a two-dimensional harmonic oscillator using the Schrodinger equation. One participant is unsure which equation to use, while the other suggests using the potential function to find the eigenvalues and eigenfunctions. They also mention that the energy of the oscillator is the sum of the one-dimensional energy eigenvalues.

You plug the potential into the Schrodinger equation and solve for the eigenvalues and eigenfunctions.
 
  • #3
The two-dimensional oscillator can be considered as two independent one-dimensional ones, according to the potential function (x and y are not mixed). Both oscillators have eigenvalues in the form of hf(n+1/2). (f is the frequency of the oscillator). You can see from the potential function how the oscillator frequencies are related. The energy of the oscillator is the sum of the one-dimensional energy eigenvalues.

FAQ: What is the Eigenvalue Equation for a 2D Harmonic Oscillator?

What is an eigenvalue of a harmonic oscillator?

An eigenvalue of a harmonic oscillator is a characteristic value that represents the energy levels of the oscillator. It is also known as a quantized energy level.

How is the eigenvalue of a harmonic oscillator calculated?

The eigenvalue of a harmonic oscillator is calculated using the Schrodinger equation, a mathematical equation used to describe the behavior of quantum particles. It takes into account the mass, frequency, and potential of the oscillator.

What is the significance of the eigenvalue in a harmonic oscillator?

The eigenvalue in a harmonic oscillator represents the allowed energy levels of the oscillator. It provides insight into the quantization of energy and how it affects the behavior of the system.

How does the eigenvalue change with different parameters in a harmonic oscillator?

The eigenvalue of a harmonic oscillator is directly proportional to the frequency of the oscillator and is inversely proportional to the mass of the particle and the strength of the potential. This means that changing any of these parameters will result in a change in the eigenvalue.

Can the eigenvalue of a harmonic oscillator be negative?

No, the eigenvalue of a harmonic oscillator cannot be negative. This is because the energy levels of the oscillator are quantized and can only take on discrete values. Negative energy levels are not allowed in quantum mechanics.
