Introduction to Causal Dynamical Triangulations

Causal Dynamical Triangulation (CDT) is a background independent approach to quantum gravity. In this introductory talk, we present basics of the CDT model in four dimensions. We show that the dynamically emerging background geometry corresponds to the maximally symmetric solution of vacuum Einstein equations - de Sitter spacetime. In this framework no degrees of freedom were frozen, however, the obtained effective action agrees with the "minisuperspace" model.
