For subsection 3 of exercise 4:
The given answer was:
It seems as if the vector was constructed with
(Found this with chatgpt), is this right? And if yes, how and why exactly could you come to this relation? (I understand the alpha, but not the overall form)
Hi Iris,
Your wavefunction is formed by a vector (\phi_1,\phi_2,\phi_3,\phi_4). Using the given relation \phi_{i+1}=e^{i\alpha}\phi_i you can rewrite the vector in terms of only \phi_1. With that, I think you might see how to proceed already. Let me know if this helps.
