comment Graph of electric potential
The plot you have for electric potential is drawn for a point-like charge. For a finite sized charged particle the field inside the charged particle indeed does not diverge. For example for a hollow sphere with some charge, the potential is constant inside the sphere and outside the sphere follows the behavior shown in your figure.

Can you please post your equations and Lagrangian here.

Can you give us your definition of $Z$?

comment Proof that eigenvalues of Fermionic creation/annihilation operators are Grassman numbers
From the books at my hand at the moment at least Altland & Simons "Condensed matter field theory" and Peskin & Schröder "Introduction to QFT" do this.

comment Proof that eigenvalues of Fermionic creation/annihilation operators are Grassman numbers
I'm not sure if I understand this explanation, but this is probably just my own ignorance since I don't know anything about supermanifolds. Can you recommend any sources for reading about this stuff?

comment Intuitive explanation to why superconductivity breaks at high temperatures
Actually if I think about it, my question could be rephrased as: why is there a temperature dependence in the gap? Yes, I can see from the gap equation that there is, but how would you interpret that information?
