Hello I have made a few minor editorial corrections to your interesting article on Quantum Spin Hall (Effect) to conform to the usual Wikipedia format. I have not changed any of the physics.
However I have just noticed that the last sentence (copied below) contains two indices for which you have not actually given the references. Since you have given six external references earlier in the article, I assume that this was an oversight. Could you please add the references?
The sentence was: All these predictions1 have been experimentally verified in a beautiful experiment2 performed in the Mollenkamp labs at Universitat Würzburg in Germany Dirac66 14:54, 13 October 2007 (UTC)
