How Does Time Dependence Influence Expectation Values in Quantum Mechanics?

Click For Summary
SUMMARY

The discussion centers on the calculation of expectation values in quantum mechanics, specifically addressing the use of the wave function \Psi(x,t) versus \psi(x). It is established that when calculating expectation values such as

and , one must utilize the time-dependent wave function \Psi(x,t) to accurately incorporate the time parameter. This ensures that the calculations reflect the dynamics of the quantum system under consideration.

If [tex]\Psi (x,t) = \psi (x) g(t)[/tex], should I then use [tex]\Psi[/tex] or [tex]\psi[/tex] when calculating [tex]<p>[/tex] and [tex]<p ^2>[/tex]?
 
Physics news on Phys.org
you should use the [tex]\Psi(x,t)[/tex] while calculating expectation value
it should include t parameter
