@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?

comment Mean field approach to toric code
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.

comment Laplacian of a delta function as an interaction potential for Laughlin state
I am aware of that definition, but I don't think that is quite equivalent to a two dimensional delta function, maybe a delta function for analytic complex functions.

comment Laplacian of a delta function as an interaction potential for Laughlin state
The situation I am concerned is that when you treat the delta function as a limiting case of a Gaussian function(say if we want to investigate the interaction range for this Laplacian of the delta function), then if z is the only variable wouldn't make sense.

comment The bijective correspondence between a symmetric polynomial and edge excitation of the fractional quantum hall droplet
Thanks for clearing that part up, Prof. Wen. I am glad that I can directly ask you question this way. I do have one more question on that fascinating paper. The wave function $\prod_i (1-\frac{z_i}{\xi})^n$ you proposed for the interaction between a outside 'charge' n at $\xi$ and the FQH droplet, can we just thought that as a 'charge' n/m quasihole, since the wave function will be almost the same.

Any paper on that I can read about?

comment $\theta$ term of anomaly related with topological insulators
Could you explain a little more how this is related to the Chern-Simon term?
