Quantum torsion and a Hartle-Hawking beam

چکیده

In the Einstein-Cartan framework torsion-free conditions arise within Hamiltonian treatment as second-class constraints. The standard strategy is to solve these constraints, eliminating torsion from classical theory, before quantization. Here we advocate leaving inside other constraints quantization, leading at first wave functions that can be called ``kinematical'' with regards torsion, but not condition then imposed a upon physical packets one constructs, satisfying usual uncertainty relations, and so room for quantum fluctuations in torsion. This alternative has surprising effect of clarifying sense which solving an explicitly real theory are ``delta-function normalizable''. Such solutions zero (or any fixed) should interpreted plane waves space. Properly constructed therefore normalizable sense. Given they canonical duals, this statement applies equally well Chern-Simons state (connection representation) Hartle-Hawking function (metric representation). We show how, when taken into account, replaced by Gauss-Airy function, finite norm, call beam. state, instead, becomes packet Gaussian probability distribution connection conclude paper two sections explaining how generalize results beyond minisuperspace.

Hartle-Hawking Wave Function

In most attempts to compute the Hartle-Hawking “wave function of the universe” in Euclidean quantum gravity, two important approximations are made: the path integral is evaluated in a saddle point approximation, and only the leading (least action) extremum is taken into account. In (2+1)dimensional gravity with a negative cosmological constant, the second assumption is shown to lead to incorrec...

A Note on Hartle-Hawking Vacua

The purpose of this note is to establish the basic properties— regularity at the horizon, time independence, and thermality—of the generalized Hartle-Hawking vacua defined in static spacetimes with bifurcate Killing horizon admitting a regular Euclidean section. These states, for free or interacting fields, are defined by a Euclidean functional integral on half the Euclidean section. The emphas...

Hartle-Hawking Wave-Function for Flux Compactifications

We argue that the topological string partition function, which has been known to correspond to a wave-function, can be interpreted as an exact “wave-function of the universe” in the mini-superspace sector of physical superstring theory. This realizes the idea of Hartle and Hawking in the context of string theory, including all loop quantum corrections. The mini-superspace approximation is justi...

Hartle-Hawking state in supersymmetric minisuperspace

The Hartle-Hawking ‘no-boundary’ state is constructed explicitely for the recently developed supersymmetric minisuperspace model with non-vanishing fermion number. Spatially homogeneous models both in gravity and in supergravity have enjoyed some popularity in recent years as a testing ground for new ideas in quantum cosmology. One such idea, which has been discussed extensively in the literatu...

Real Tunneling Solutions and the Hartle-Hawking Wave Function

A real tunneling solution is an instanton for the Hartle-Hawking path integral with vanishing extrinsic curvature (vanishing “momentum”) at the boundary. Since the final momentum is fixed, its conjugate cannot be specified freely; consequently, such an instanton will contribute to the wave function at only one or a few isolated spatial geometries. I show that these geometries are the extrema of...
