Correction to week 4 Ex. 4.b

Hi, This comes pretty late, but I say it anyway. There was a minor mistake in the example solutions for week 4 Exercise 4.b. k_y was mistakenly labelled as k_z in a lot of places. Also I hinted the existence of certain intermediate steps which in reality were non-existing (There was a note “see (4) below” although there was no “(4)” to be found). I updated the example solutions and these issues are now fixed. -Lauri

Hi, Notice that some little hints were added to this weeks assignments on QM2 (refresh the page). Also the last two exercises (4 and 5) were divided into a and b parts. If you already did some of the last exercises, you can just leave your solution as it was. Lauri, teacher assistant

Correction to example solution

Hi, As some of you have probably noticed (thank you for the feedback!), there was a silly mistake in QM2 third week example solution number 4. We of course have sin^2(x) --> 0 instead of sin^2(x) --> 1 when x goes to 0. I corrected the example solution. The arguments are now different, but we still have that perturbation theory doesn't work when omega = delta omega (this time it's due to unbounded probability rather than infinite probability).

Hi, I would just like to point out the following: in addition to attending the weekly exercise sessions it is also totally okay to send me a message and ask about the QMII exercises. I say this because it often feels like the students are a bit shy to ask although there's no need to. If you are wondering should you send a message or not, just send it (even if the day was like Saturday). You can send me message via - email ( laaajoke(a)student.jyu.fi or laaajoke(a)jyu.fi ) or - phone (044 990 1371, WhatsApp, Telegram, Signal). Your T.A. (teacher assistant) on this course, Lauri
