In a previous thread a member asked a question about the following probability formula <ΨE|P|Ψg>
I would like to exploit his formula to ask some very basic questions about the meaning of this formula.
Here are my questions...
1. Is | Ψg> the wave function for the ground state of the system?
1a. Looked at in terms of simple linear algebra, is it just a column vector?
1b. What does each element in the column vector represent?
2. When you operate on the ground state with the momentum operator, as in P|Ψg>, is the result another column vector?
2a. What do the elements of that column vector represent?
3. In terms of linear algebra, what does the following Dirac notation mean... |A,B>?
I may have more questions...
