On 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 کاملMultiparametric Quantum Algebras and the Cosmological Constant
With a view towards applications for de Sitter, we construct the multi-parametric qdeformation of the so(5,C) algebra using the Faddeev-Reshetikhin-Takhtadzhyan(FRT) formalism. [email protected] [email protected]
متن کاملGravitation, the Quantum, and Cosmological Constant
The arguments of statistical nature for the existence of constituents of active gravitational masses are presented. The present paper proposes a basis for microscopic theory of universal gravitation. Questions like the relation of cosmological constant and quantum theory, black hole radiance and the nature of inertia are addressed. This paper is the second in the series of papers published in 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...
متن کاملQuantum gravity with a positive cosmological constant
A quantum theory of gravity is described in the case of a positive cosmological constant in 3 + 1 dimensions. Both old and new results are described, which support the case that loop quantum gravity provides a satisfactory quantum theory of gravity. These include the existence of a ground state, discoverd by Kodama, which both is an exact solution to the constraints of quantum gravity and has a...
