Quantum Gravity: a Progress Report
The problem of reconciling general relativity and quantum theory has fascinated and bedeviled physicists for more than 70 years. Despite recent progress in string theory and loop quantum gravity, a complete solution remains out of reach. I review the status of the continuing effort to quantize gravity, emphasizing the underlying conceptual issues and the various attempts to come to grips with t...
متن کاملKnots and Quantum Gravity: Progress and Prospects
Recent work on the loop representation of quantum gravity has revealed previously unsuspected connections between knot theory and quantum gravity, or more generally, 3-dimensional topology and 4-dimensional generally covariant physics. We review how some of these relationships arise from a ‘ladder of field theories’ including quantum gravity and BF theory in 4 dimensions, Chern-Simons theory in...
متن کاملBackground Independent Quantum Gravity: A Status Report
The goal of this article is to present an introduction to loop quantum gravity —a background independent, non-perturbative approach to the problem of unification of general relativity and quantum physics, based on a quantum theory of geometry. Our presentation is pedagogical. Thus, in addition to providing a bird’s eye view of the present status of the subject, the article should also serve as ...
متن کاملTopological Quantum Field Theory : a Progress Report
A brief introduction to Topological Quantum Field Theory as well as a description of recent progress made in the field is presented. I concentrate mainly on the connection between Chern-Simons gauge theory and Vassiliev invariants, and Donaldson theory and its generalizations and Seiberg-Witten invariants. Emphasis is made on the usefulness of these relations to obtain explicit expressions for ...
متن کاملCanonical quantum gravity with new variables and loops: a report
The relationship of quantum mechanics and gravity has been a problematic one since the early attempts to quantize the theory of general relativity. There are a plethora of prima facie difficulties (see [1] for a summary) that one faces even before laying down any specific approach to the subject. This has discouraged many people away from the field. On the other hand, it is not healthy to just ...
