Triangulations is a leading nonstring QG approach which is among the least known, where we have to most catching-up to do to follow it. The name is short for CAUSAL DYNAMICAL TRIANGULATIONS (CDT). If you want to join me in studying up on CDT in early 2008 then the articles to print off so you have hardcopy to scribble are: http://arxiv.org/abs/0711.0273 (21 pages) The Emergence of Spacetime, or, Quantum Gravity on Your Desktop "Is there an approach to quantum gravity which is conceptually simple, relies on very few fundamental physical principles and ingredients, emphasizes geometric (as opposed to algebraic) properties, comes with a definite numerical approximation scheme, and produces robust results, which go beyond showing mere internal consistency of the formalism? The answer is a resounding yes: it is the attempt to construct a nonperturbative theory of quantum gravity, valid on all scales, with the technique of so-called Causal Dynamical Triangulations. Despite its conceptual simplicity, the results obtained up to now are far from trivial. Most remarkable at this stage is perhaps the fully dynamical emergence of a classical background (and solution to the Einstein equations) from a nonperturbative sum over geometries, without putting in any preferred geometric background at the outset. In addition, there is concrete evidence for the presence of a fractal spacetime foam on Planckian distance scales. The availability of a computational framework provides built-in reality checks of the approach, whose importance can hardly be overestimated." http://arxiv.org/abs/0712.2485 (10 pages) Planckian Birth of the Quantum de Sitter Universe "We show that the quantum universe emerging from a nonperturbative, Lorentzian sum-over-geometries can be described with high accuracy by a four-dimensional de Sitter spacetime. By a scaling analysis involving Newton's constant, we establish that the linear size of the quantum universes under study is in between 17 and 28 Planck lengths. Somewhat surprisingly, the measured quantum fluctuations around the de Sitter universe in this regime are to good approximation still describable semiclassically. The numerical evidence presented comes from a regularization of quantum gravity in terms of causal dynamical triangulations." There are some three or so other earlier papers that have explanations of the actual set up and the computer runs, they are from 2001, 2004, 2005. I will get the links later. Have to go out at the moment but will get started with this soon.
