Lecture 1 | 🗖 nosplit | ↑ parent "Quantum field theory lecture by Tobias Osborne published in 2017" | 225
- Quantum Field Theory lecture notes by David Tong (2007) is the course basis
- quantum field theory in a nutshell by Anthony Zee (2010) is a good quick and dirty book to start
Non-relativistic QTF is a limit of relativistic QFT, and can be used to describe for example condensed matter physics systems at very low temperature. But it is still very hard to make accurate measurements even in those experiments.
Mentions that "QFT is hard" because (a finite list follows???):
There are no nontrivial finite-dimensional unitary representations of the poincare group.But I guess that if you fully understand what that means precisely, QTF won't be too hard for you!
