Cosmology of the Jackiw - Teitelboim model
We investigate the cosmology of the two-dimensional Jackiw-Teitelboim model. Since the matter coupling is not defined uniquely, we consider two possible choices. The dilaton field plays an important role in the discussion of the properties of the solutions. In particular, the possibility of universes having a finite initial size emerges.
متن کاملOn the cosmological constant in quantum cosmology
Quantization of a dust-like closed isotropic cosmological model with a cosmological constant is realized by the method of B. DeWitt [1]. It is shown that such quantization leads to interesting results, in particular, to a finite lifetime of the system, and appearance of the Universe in our world as penetration via the barrier. These purely quantum effects appear when Λ > 0. Quantization of cosm...
متن کاملThe Cosmological Constant in Brane Cosmology
We propose, based on brane cosmology, an explicit relation R = MPlR 2 extra of the radius of the observed brane Universe and the extra dimensions for solving both the hierarchy problem and the cosmological constant problem without fine-tuning. This relation associates the dark energy (i.e., cosmic acceleration) in the cosmological physics with the electroweak scale in particle physics, thereby ...
متن کاملIntroduction to Cosmology and the Cosmological Constant
This paper is written for the course apm426S, taught by James Colliander in Spring 2002, University of Toronto. It gives an introduction to cosmology, concentrating on the effects of the cosmological constant Λ in the context of isotropic and homogeneous universe. Solutions to the Einstein’s equation with and without Λ are carefully derived, analyzed and compared. Some current problems with Λ a...
متن کاملCosmological Constant Seesaw in Quantum Cosmology
Recently a phenomenological relationship for the observed cosmological constant has been discussed by Motl and Carroll in the context of treating the cosmological constant as a 2× 2 matrix but no specific realization of the idea was provided. We realize a cosmological constant seesaw mechanism in the context of quantum cosmology. The main observation used is that a positive cosmological constan...
