@NorbertSchuch So extensive GSD=gapless state?

@MengCheng Could you elaborate on why the phase is not gapped?

comment Wen plaquette model with one kind of plaquette operator
As you know, Wen's plaquette model is nothing but the toric code and you can transform it into a version with plauqette operators $\sigma^z$ $\sigma^z$ $\sigma^z$ $\sigma^z$ on even sublattice and $\sigma^x$ $\sigma^x$ $\sigma^x$ $\sigma^x$ on odd sublattice. I am here asking what if you are left with only one on all plaquettes?

comment Mean field approach to toric code
Is u in the mean field theory a constant from the other expectation values or should it depend on the position $ij$ of the link?

What is the relation of Majorana fermions dimerized and the spectrum being gapped?

Thanks Everett for the detailed answer. By the way, do you know where can I look into for reference about all the results listed in your last paragraph?

comment Wick's theorem for calculating OPE
I guess I am just confused about what exactly should $T(z)\partial_z \phi$ be equal to using Wick's theorem.
