Course outline given:
🔗
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.
🔗
Defines "relativistic" as: "the Lagrangian is symmetric under the Poincare group".
🔗
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!
🔗
Notably, this is stark contrast with rotation symmetry groups (SO(3)) which appears in space rotations present in non-relativistic quantum mechanics.
