PROFESSOR: Here is your potential. It's going to be a smooth, nice potential like that. V of x. x, x. And now, suppose you don't know anything about the energy eigenstates. Now, this potential will be assumed to be symmetric. So here is one thing you can do. You can exploit some things that you know about this potential. And here's the wave functio... Read More
Questions & Answers
Q: What are energy eigenstates in quantum mechanics?
Energy eigenstates are the possible states of a quantum system that correspond to specific energy values. They are represented by wave functions that satisfy the Schrodinger equation for a given potential.
Q: How should the wave function of an energy eigenstate behave on the right and left of a potential?
On the right of the potential, the wave function should match the forbidden region wave function. On the left, it should decay, but the specific form of decay depends on the behavior in the middle of the potential.
Q: What is the shooting method in quantum mechanics?
The shooting method is a numerical approach for finding energy eigenstates. It involves iteratively adjusting the energy value and solving the Schrodinger equation until a normalizable wave function is obtained.
Q: How does the shooting method work for finding energy eigenstates?
In the shooting method, an initial energy value is chosen, and the Schrodinger equation is solved with boundary conditions on the wave function and its derivative. By adjusting the energy value and observing the behavior of the wave function, a suitable energy eigenstate can be found.
