Thank you advance for help!
So the problem is find <x> in P space.
The solution's logic is use formula:
The submit with
Then one will get the integral
by noticing that
, one can replace xeipx/ħ in the integral
so that
and then after solving the integral one can find the expectation value for x.
The part I don't understand is why
, firstly I am not sure where is the minus sign comes from. Next I don't think I can just change the order of eipx/ħ and Φ because the term d/dp.
Could anyone help me figure the integral out?
Thank you everybody.
