causal dynamical triangulation造句

• She received her Ph . D . from Causal Dynamical Triangulations.
• Another approach to quantum gravity that is closely related to causal dynamical triangulation is called causal sets.
• It is closely related to background independent quantum gravity approaches such as loop quantum gravity, the spin foam formalism and causal dynamical triangulation.
• The theory of Causal Dynamical Triangulations faced harsh scrutiny for some years because most physicists preferred models that required more dimensions and a fixed background.
• He is known for his work on ( 2 + 1 )-dimensional quantum gravity, the quantum gravitational basis of black hole thermodynamics, and causal dynamical triangulations.
• In May 2006, Markopoulou published a paper with Lee Smolin that further popularized this Causal Dynamical Triangulation ( CDT ) Theory by explaining time slicing of the Ambjorn Loll CDT model as result of gauge fixing.
• In July 2008, Scientific American featured an article on Causal dynamical triangulation, written by the three scientists who propounded the theory, which again suggests that the universe may have the characteristics of a fractal.
• And while Linde s theory shows fractality at scales likely larger than the observable universe, theories like Causal dynamical triangulation and Scale Relativity published in 1992, and published a book on the subject of Fractal Space-Time in 1993.
• And each of the various theories of the microscale universe, or of gravity, from String theory and LQG to Causal Dynamical Triangulation all include the idea of different dimensionality near the Planck Scale ( ranging from 2 to 10 or 11 dimensions ).
• If one reads the recent article on Causal dynamical triangulation in Scientific American, for instance, it is readily apparent that the authors of that theory are quite aware their work has profound implications for Cosmology, though it was originally framed as a theory of Quantum Gravity.
• "' Causal dynamical triangulation "'( abbreviated as "'CDT "') invented by Renate Loll, Jan Ambj鴕n and Jerzy Jurkiewicz, and popularized by Fotini Markopoulou and Lee Smolin, is an approach to quantum gravity that like loop quantum gravity is background independent.
• An article by Alexander Hellemans in the August 2006 issue of Scientific American quotes Connes as saying that the next important step toward this goal is to " try to understand how space with fractional dimensions couples with gravitation . " The work of Connes with physicist Carlo Rovelli suggests that time is an emergent property or arises naturally, in this formulation, whereas in Causal dynamical triangulation, choosing those configurations where adjacent building blocks share the same direction in time is an essential part of the'recipe .'Both approaches suggest that the fabric of space itself is fractal, however.
