Quantum Bound States
| Explore the properties of quantum "particles" bound in potential wells. See how the wave functions and probability densities that describe them evolve (or don't evolve) over time. |
Teaching Resources
Main Topics
- Quantum Particles
- Potential Wells
- Waves
- Probability Density
Sample Learning Goals
- Visualize wave functions, probability densities, and energy levels for bound states in various potentials.
- Describe how multiple representations used for wave functions relate to one another.
- Explain what is and is not time-dependent for an energy eigenstate and a superposition state.
- Predict how the curvature and amplitude of the wave function and the spacing of the energy levels depends on the shape of the potential and the mass of the particle.
- Gain an intuition for how band structure results in a lattice of many wells.
- Gain an intuition for how to go from the microscopic potential of a single atom to the macroscopic potential of a solid.
