To study the nature of Hawking radiation, there are two useful approaches. One way is to treat quantum fluctuations of a field on the classical curved background [2].

The other way is to use the Euclidean path integral and obtain some thermodynamic quantities by the Wick. Format: PDF, ePub Category: Science Languages: en Pages: View: Get Book.

Euclidean vs. Lorentzian quantum gravity Daniel Harlow MIT Janu 1. Introduction Introduction In quantum mechanics there are two kinds of path integrals that we like: Euclidean path integral: thermal equilibrium, xed-time correlators. Lorentzian path integral: scattering theory, out-of-equilibrium dynamics, chaos, etc. For ordinary quantum systems there isn’t much conceptual di.

In these lectures I am going to describe an approach to Quantum Gravity using path integrals in the Euclidean regime i.e. over positive definite metrics. (Strictly speaking, Riemannian would be more appropriate but it has the wrong connotations). The motivation for this is the belief that the topological properties of the gravitational fields play an essential role in Quantum Theory.

Attempts Cited by: An indirect way of observing quantum gravity e ects is via the gauge / gravity corre-spondence, which relates quantum eld theories and quantum gravity.

Euclidean quantum gravity refers to a Wick rotated version of quantum gravity, formulated as a quantum field theory. The manifolds that are used in this formulation are 4-dimensional Riemannian manifolds instead of pseudo Riemannian manifolds. It is also assumed that the manifolds are compact, connected and boundaryless (i.e. no singularities). Following the usual quantum field-theoretic.

First-order action and Euclidean quantum gravity Since the original work of Gibbons and Hawking [5] many proposals for infinite counter-terms have been proposed. See e.g. [3,6,9–13]. Unfortunately, the counterterm subtraction method depends crucially on the topology of the system under consideration, as well as on the matter content of the stress-energy (e.g.

Request PDF | Euclidean Wormholes in Horava-Lifshitz Gravity | We study Euclidean wormholes in the framework of the Horava-Lifshitz theory of gravity.

Euclidean wormholes first appeared in the. This is a collection of survey lectures and reprints of some lectures on the Euclidean approach to quantum gravity in which one expresses the Feynman path integral as a sum over Riemannian metrics. Also included are sections on Black Holes, quantum cosmology, wormholes and gravitational instantons. The term is required to ensure the path integral (a la Hawking) for quantum gravity has the correct composition properties.

When calculating black hole entropy using the Euclidean semiclassical approach, the entire contribution comes from the GHY term. This term has had more recent applications in loop quantum gravity in calculating transition amplitudes and background-independent scattering.

The bulk quantum geometrodynamics is provided by the Ponzano–Regge state-sum model, which defines 3D quantum gravity as a discrete topological quantum field theory (TQFT). This formulation provides an explicit and detailed definition of the quantum boundary states, which allows a rich correspondence between quantum boundary conditions and boundary theories, thereby leading to.
