Can I do anything instructive by simulating QED on a lattice?
For learning something about the degrees of freedom and underlying path integral math, is it possible to do some kind of scalar QED or normal QED simulation on a lattice in the same way Lattice QCD is ...

Gauss law with staggered fermions
I was wondering if someone could explain how to derive the discrete version of Gauss law in 1+1 QED using staggered Fermions.
The result I am trying to reproduce is found in multiple references [see ...

Proof of commutation relation for lattice QFT
How do you prove the following commutation relation for the lattice QFT
\begin{equation}
[\phi(X),\Pi(y)]=\text{i}a^{-d}\delta_{x,y}\mathbb{I}?
\end{equation}
