Consistent Discretization and Canonical Classical and Quantum Regge Calculus
نویسندگان
چکیده
We apply the “consistent discretization” technique to the Regge action for (Euclidean and Lorentzian) general relativity in arbitrary number of dimensions. The result is a well defined canonical theory that is free of constraints and where the dynamics is implemented as a canonical transformation. In the Lorentzian case, the framework appears to be naturally free of the “spikes” that plague traditional formulations. It also provides a well defined recipe for determining the integration measure for quantum Regge calculus.

A new discretization of classical and quantum general relativity
We propose a new discrete approximation to the Einstein equations, based on the Capovilla-Dell-Jacobson form of the action for the Ashtekar variables. This formulation is analogous to the Regge calculus in that the curvature has support on sets of measure zero. Both a Lagrangian and Hamiltonian formulation are proposed and we report partial results about the constraint algebra of the Hamiltonia...
متن کاملDiscretization and Continuum Limit of Quantum Gravity on a Four-Dimensional Space-Time Lattice
The Regge Calculus is a powerful method to approximate a continuous manifold by a simplicial lattice, keeping the connectivities of the underlying lattice fixed and taking the edge lengths as degrees of freedom. The Discrete Regge Model limits the choice of the link lengths to a finite number. We examine the phase structure of Standard Regge Calculus in four dimensions and compare our Monte Car...
متن کاملLatticing Quantum Gravity
I discuss some aspects of a lattice approach to canonical quantum gravity in a connection formulation, discuss how it differs from the continuum construction, and compare the spectra of geometric operators – encoding information about components of the spatial metric – for some simple lattice quantum states. 1 To appear in the Proceedings of the 2nd Conference on Constrained Dynamics and Quantu...
متن کاملDiscrete Approaches to Quantum Gravity in Four Dimensions
The construction of a consistent theory of quantum gravity is a problem in theoretical physics that has so far defied all attempts at resolution. One ansatz to try to obtain a non-trivial quantum theory proceeds via a discretization of space-time and the Einstein action. I review here three major areas of research: gauge-theoretic approaches, both in a path-integral and a Hamiltonian formulatio...
متن کاملUmbral Calculus, Discretization, and Quantum Mechanics on a Lattice
Umbral calculus’ deals with representations of the canonical commutation relations. We present a short exposition of it and discuss how this calculus can be used to discretize continuum models and to construct representations of Lie algebras on a lattice. Related ideas appeared in recent publications and we show that the examples treated there are special cases of umbral calculus. This observat...
