I recall reading the first experimental paper on analog gravitational black holes being created using bose einstein condensates(<a href="http:&#x2F;&#x2F;journals.aps.org&#x2F;prl&#x2F;abstract&#x2F;10.1103&#x2F;PhysRevLett.105.240401" rel="nofollow">http:&#x2F;&#x2F;journals.aps.org&#x2F;prl&#x2F;abstract&#x2F;10.1103&#x2F;PhysRevLett.105...</a>), and was happy to see the work continuing here (see referenced paper in the article: <a href="http:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;1510.00621" rel="nofollow">http:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;1510.00621</a>).<p>What was very surprising was that it was a single author paper (only the prof of the group). These sort of research efforts are usually Prof+possible postdoc+a few grad students. Not sure if prof is leaving grad students out (I hope not!), or is toiling alone at this work.
