Abstract

Quantum cosmology and gravity are defined here as the primary and secondary quantizations of the energy constraints by analogy with the historical formulation of quantum field theory given in the 20th century. A new fact is that both the Universe and its matter are created from stable vacuum obtained by the Bogolyubov transformations applied to description of quantum superfluid liquid. We show that the quantum gravity makes it possible to explain topical problems of cosmology by the cosmological creation of both universes and particles from Bogolyubov's vacuum.

Time and the interpretation of canonical quantum gravity

Journal Article Unruh, W; Wald, R - Physical Review (Section) D: Particles and Fields; (USA)

The unsatisfactory status of the interpretation of the wave function of the Universe in canonical quantum gravity is reviewed. The naive interpretation'' obtained by straightforwardly applying the standard interpretive rules to the canonical quantization of general relativity is manifestly unacceptable; the WKB interpretation'' has only a limited domain of applicability; and the conditional probability interpretation'' requires one to pick out a preferred time variable'' (or preferred class of such variables) from among the dynamical variables. Evidence against the possibility of using a dynamical variable to play the role of time'' in the conditional probability interpretation is provided by the factmore »« less

Quantum gravity

Journal Article Renteln, P

General relativity and quantum mechanics are the two great pillars that form the foundation of 20th-century physics, and yet their precepts assume two different kinds of universe. Are the two theories compatible Can they ever be reconciled in a self-consistent theory of quantum gravity The pursuit of quantum gravity poses an immense challenge to theorists. The application of standard ideas to the quantization of gravity either yields nonsensical theories or else requires mathematical techniques that have yet to be developed. Even so, the efforts have borne some fruit. Hawking radiation, for example, reveals the presence of a deep connection betweenmore »« less

Further improvements in the understanding of isotropic loop quantum cosmology

Journal Article Martin-Benito, M; Mena Marugan, G; Olmedo, J - Physical Review. D, Particles Fields

The flat, homogeneous, and isotropic universe with a massless scalar field is a paradigmatic model in loop quantum cosmology. In spite of the prominent role that the model has played in the development of this branch of physics, there still remain some aspects of its quantization which deserve a more detailed discussion. These aspects include the kinematical resolution of the cosmological singularity, the precise relation between the solutions of the densitized and nondensitized versions of the quantum Hamiltonian constraint, the possibility of identifying superselection sectors which are as simple as possible, and a clear comprehension of the Wheeler-DeWitt (WDW) limitmore »« less

Simulating 0+1 Dimensional Quantum Gravity on Quantum Computers: Mini-Superspace Quantum Cosmology and the World Line Approach in Quantum Field Theory

Conference Kocher, Charles; McGuigan, Michael

Quantum computers are promising candidates to radically expand the domain of computational science by their increased computing power and more effective algorithms. In particular, quantum computing could have a tremendous impact on the field of quantum cosmology. The goal of quantum cosmology is to describe the evolution of the universe through the Wheeler-DeWitt equation or path integral methods without having to first formulate a full theory of quantum gravity. The quantum computer provides an advantage in this endeavor because it can perform path integrals directly in Lorentzian space and does not require constructing contour integrations in Euclidean gravity. Also, quantummore »« less
