Homework Statement
i. Confirming the wavefunction is normalised
ii. Calculating the expectation values: [tex]<\hat{x}> , <\hat{x^{2}}> , <\hat{p}> , <\hat{p^{2}}>[/tex] as a function of [tex]\sigma[/tex]
iii. Interpreting the results in regards to Heisenberg's uncertainty relation.
Homework Equations
wave function [tex]\psi(x) = (2\pi\sigma)^{\frac{-1}{4}}exp[\frac{-x^{2}}{4\sigma}][/tex]
The Attempt at a Solution
i. I know that a wave function [tex]\psi(x)[/tex] is normalised if:
[tex]|\psi(x)|^{2} = 1[/tex]
So I have tried to modulus [tex]\psi(x)[/tex] and then square it, but this doesn't equal to 1. Or at least I'm just doing it wrong.. I'm thinking maybe have to take the real part of the exponential term in the equation.. or something like that, but I don't know.
ii. I'm not sure how to calculate these for this wave function.
