Covariance, relativity, and the proper mass of the universe in the no-boundary wave function
Natalia Gorobey, Alexander Lukyanenk, A. V. Goltsev
A discrete class of privileged reference frames in a closed universe with identical equations of motion for physical degrees of freedom was found. A representation of the quantum s…
CPT symmetry in the mirror universe
Natalia Gorobey, Alexander Lukyanenko, A. V. Goltsev
A model of a two-sheeted universe in the quantum theory of gravity is proposed, based on the definition of 3D invariant and gauge-invariant proper time of the universe. A uniform t…
Observer in quantum cosmology
Natalia Gorobey, Alexander Lukyanenko, Alexander V. Goltsev
Within the framework of the new formalism of quantum theory - the quantum principle of least action - the initial state of the universe is determined, which is an analogue of the H…
Quantum Principle of Least Action in Dynamic Theories With Higher Derivatives
Natalia Gorobey, Alexander Lukyanenko, A. V. Goltsev
A generalized canonical form of action of dynamic theories with higher derivatives is proposed, which does not require the introduction of additional dynamic variables. This form i…
No-boundary Wave Functional and Own Mass of the Universe
Natalia Gorobey, Alexander Lukyanenko, A. V. Goltsev
An alternative formulation of the no-boundary initial state of the universe in the Euclidean quantum theory of gravity is proposed. Unlike the no-boundary Hartle-Hawking wave funct…
