... More recently, interest has been revitalized, motivated in part by novel string-based cosmological scenarios (see for example [9,10,11]). Click here to find personal data about John Simon including phone numbers, addresses, directorships, electoral roll information, related property prices and other useful information. Based on Nielsen’s geometric approach to quantum circuit complexity, we find the variation only depends on the end of the optimal circuit. We obtain two families of smooth solutions which contains all the known solutions, new solutions called nullbranes, and solutions interpolating between them. arXiv:0710.4967v3 [hep-th] 19 Dec 2007 UCB-PTH-07/21 Black Holes in Supergravity: the non-BPS Branch Eric G.

Julian Sonner (DAMTP, Cambridge) Geometric phases in string theory. Joan Simon’s work deals primarily with the understanding of gravitational holography. Joan is general relativity and the Landau problem in and ; in particular, the classical geodesics correspond to Larmor orbits in the Landau problem. MIGSAA.
