The Wheeler-DeWitt equation is based on the use of canonical quantization rules that may be inconsistent for constrained dynamical systems, such as minisuperspaces subject to Einstein's equations. The resulting quantum dynamics has no classical limit and it suffers from the infamous ``problem of time.'' In this article, it is shown how a dynamical time (an internal clock) can be constructed by means of a Hamilton-Jacobi formalism, and then used for a consistent canonical quantization, with the… 

Minisuperspace Quantization of f(T, B) Cosmology

We discuss the quantization in the minisuperspace for the generalized fourth-order teleparallel cosmological theory known as fT, B. Specifically we focus on the case where the theory is linear on the

We present a stochastic framework for emergent quantum gravity coupled to matter. The Hamiltonian constraint in diffeomorphism-invariant theories demands the identification of a clock relative to

The Wheeler-DeWitt equation as an eigenvalue problem for the cosmological constant

The Standard Cosmological Model with energy density ρ, pressure p and cosmological term λ is reconsidered. The interdependence among the cosmological equations in different equivalent forms is

An approach to the quantization of gravity in the presence of matter is examined which starts from the classical Einstein–Hilbert action and matter approximated by “point” particles minimally coupled

Time without time: A stochastic clock model

We study a classical reparametrization-invariant system, in which ``time'' is not a priori defined. It consists of a nonrelativistic particle moving in five dimensions, two of which are compactified

Quantum Jumps Revisited

A theoretical description of quantum jumps at the level of elementary particles is proposed, based on a micro-cosmological interpretation of their de Broglie phase. The third quantization formalism

Unitary and nonunitary evolution in quantum cosmology

We analyse when and why unitarity violations might occur in quantum cosmology restricted to minisuperspace. To this end we discuss in detail backscattering transitions between expanding and

Similarity solutions for the Wheeler–DeWitt equation in $$f\left( R\right) $$-cosmology

In the case of a spatially flat Friedmann–Lemaître–Robertson–Walker Universe in $$f\left( R\right) $$fR-gravity we write the Wheeler–DeWitt equation of quantum cosmology. The equation depends upon

Einstein's theory of gravity is reformulated so that the cosmological constant becomes an integration constant of the theory, rather than a coupling'' constant, and the key weakness'' of this formulation is that one must introduce a nondynamic background spacetime volume element.


We discuss how to fix the gauge in the canonical treatment of Lagrangians, with a finite number of degrees of freedom, endowed with time reparametrization invariance. The motion can be described by

The paper addresses quantitatively the question of the validity of physical predictions based on minisuperspace quantization of Einstein's theory of gravitation. It studies a homogeneous, anisotropic

The canonical dynamical structure of general relativity has often been viewed as that of a parametrized field theory in which the many-fingered spacetime variables are hidden among the geometrodynamical field variables.

It is argued that the interpretive problems of quantum gravity are not alleviated by the incorporation of observers into the theory, and a proposal for a formulation of canonical quantum gravity in which an appropriate nondynamical time parameter is present is made.

No Lagrangian? No quantization!

This work starts with classical equations of motion and sets very general quantization conditions (commutation relations). It is proved that these conditions imply that the equations of motion are

Uniform semiclassical quantization of regular and chaotic classical dynamics on the Hénon–Heiles surface

Qualitative arguments (made substantially more quantitative in the accompanying article by Shirts and Reinhardt) are put forward which indicate that the apparently chaotic dynamics on the

Quantum Theory of Gravity. I. The Canonical Theory

Following an historical introduction, the conventional canonical formulation of general relativity theory is presented. The canonical Lagrangian is expressed in terms of the extrinsic and intrinsic

Approximate constants of motion for classically chaotic vibrational dynamics: Vague tori, semiclassical quantization, and classical intramolecular energy flow

Coupled nonlinear Hamiltonian systems are known to exhibit regular (quasiperiodic) and chaotic classical motions. In this and the preceding paper by Jaffe and Reinhardt, we find substantial short
