Is up on arxiv - http://arxiv.org/abs/gr-qc/0603033

Also, wikipedia is alright as a starting point for looking at something, but I personally wouldn't give much weight to opinion in the articles.

I agree that you can't trust everything that Wikipedia says, but it's a good starting point. In these cases, I also read the talk and history page, to see if there is a lot of people reading and editing the page.

In the arxiv, this article is marked as "Submitted to Physica C". I went to "Physica C" and I can't find the article. I only found three previous theoretical articles of some of the authors. ( http://www.sciencedirect.com/science?_ob=ArticleListURL&_met... )
