When we are calculating the loop corrections in our theory (QED, for instance), how does the fact that our electron is in a bound state show itself in the renormalization? Does it matter at all? If so, then why are the predicted values for the Lamb shift, which are calculated in QFT for the...
Hi, I am about to work on the problem of trying to find a renormalization program for bound states in QFT. Any suggestions/advice on where to start would be much appreciated.
Thanks for the advice. I'll keep it in mind. I'm also having time issues, that's why i tried to make the most out of his lectures without relying too much on the book. Otherwise it's one of those books you'd want to read back to back. After reviewing the notes I took of his lectures, it's given...
Hi there.
I also contacted Bender some time ago, as I was looking for some practice material for his Perimeter course. He recommended his book ( which by the way, I find to be fantastic). I'm just having a bit of a hard time pinpointing the relevant exercises to his course, because some of the...
