Linearized Quantum Gravity Using the Projection Operator Formalism
The theory of linearized general relativity is quantized using the projection operator formalism, in which no gauge choices are made. The result of this exercise is the construction of a separable, reproducing kernel for the physical Hilbert space using coherent states. The work is then compared with legacy canonical quantum gravity results.
متن کاملLinearized Gravity as a Gauge Theory
We discuss linearized gravity from the point of view of a gauge theory. In (3+1)dimensions our analysis allows to consider linearized gravity in the context of the MacDowell-Mansouri formalism. Our observations may be of particular interest in the strong-weak coupling duality for linearized gravity, in Randall-Sundrum brane world scenario and in Ashtekar formalism.
متن کاملBarbero–Immirzi field in canonical formalism of pure gravity
The Barbero–Immirzi (BI) parameter is promoted to a field and a canonical analysis is performed when it is coupled with a Nieh–Yan topological invariant. It is shown that, in the effective theory, the BI field is a canonical pseudoscalar minimally coupled with gravity. This framework is argued to be more natural than the one of the usual Holst action. Potential consequences in relation with inf...
متن کاملS-duality for Linearized Gravity
We develope the analogue of S-duality for linearized gravity in (3+1)-dimensions. Our basic idea is to consider the self-dual (anti-self-dual) curvature tensor for linearized gravity in the context of the Macdowell-Mansouri formalism. We find that the strong-weak coupling duality for linearized gravity is an exact symmetry and implies small-large duality for the cosmological constant. Pacs numb...
متن کاملRemarks on Pure Spin Connection Formulations of Gravity
In the derivation of a pure spin connection action functional for gravity two methods have been proposed. The first starts from a first order lagrangian formulation, the second from a hamiltonian formulation. In this note we show that they lead to identical results. PACS: 04.20.Cv, 04.20.Fy, 02.40.+m As shown by Ashtekar, there is a hamiltonian formulation of general relativity which uses the (...
