Dirac Quantization of Two-dimensional Dilaton Gravity Minimally Coupled to N Massless Scalar Fields
It is shown that the Callan-Giddings-Harvey-Strominger theory on S × R can be consistently quantized (using Dirac’s approach) without imposing any constraints on the sign of the gravitational coupling constant or the sign (or value) of the cosmological constant. The quantum constraints in terms of the original geometrical variables are also derived. Two-dimensional theories of gravity have been...
متن کاملA discrete nonetheless remarkable brick in de Sitter: the ''massless minimally coupled field''
Over the last ten years interest in the physics of de Sitter spacetime has been growing very fast. Besides the supposed existence of a “de sitterian period” in inflation theories, the observational evidence of an acceleration of the universe expansion (interpreted as a positive cosmological constant or a “dark energy” or some form of “quintessence”) has triggered a lot of attention in the physi...
متن کاملQuantization of the massless minimally coupled scalar field and the dS / CFT correspondence Andrew
We consider the quantization of the massless minimally coupled scalar field in de Sitter spacetime. The no-boundary Euclidean prescription naturally picks out the de Sitter invariant vacuum state of Kirsten and Garriga. We extend the dS/CFT correspondence to this case which allows us to interpret the massless field in terms of a Euclidean CFT. The extension is non-trivial and requires careful t...
متن کاملTraversable wormholes from massless conformally coupled scalar fields
The massless conformally coupled scalar field is characterized by the so-called ‘‘new improved stress-energy tensor’’, which is capable of classically violating the null energy condition. When coupled to Einstein gravity we find a three-parameter class of exact solutions. These exact solutions include the Schwarzschild geometry, assorted naked singularities, and a large class of traversable wor...
متن کاملCan cosmic acceleration be caused by exotic massless particles ?
To describe dark energy we introduce a fluid model with no free parameter on the microscopic level. The constituents of this fluid are massless particles which are a dynamical realisation of the unextended D = (3+ 1) Galilei algebra. These particles are exotic as they live in an enlarged phase space. Their only interaction is with gravity. A minimal coupling to the gravitational field, satisfyi...
