Quantum cosmology of pure connection general relativity [PDF]
Classical and Quantum Gravity, 2023 Abstract We study homogeneous cosmological models in formulations of general relativity with cosmological constant based on a (complexified) connection rather than a spacetime metric, in particular in a first order theory obtained by integrating out the self-dual two-forms in the chiral Plebański formulation.

Analytical investigation of pre-inflationary effects in the primordial power spectrum: from General Relativity to hybrid Loop Quantum Cosmology [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 This work is an analytical study of the main differences between classical inflationary effects of a fast-roll regime and imprints of hybrid Loop Quantum Cosmology (LQC) on the primordial power spectrum. Effective LQC solutions of phenomenological interest typically contain a classical period of kinetic dominance prior to slow-roll inflation, with ...

A scientometric study of general relativity and quantum cosmology from 2000 to 2012 [PDF]
Scientometrics, 2015 2015 is the centennial of Einstein General Relativity. On this occasion, we examine the General Relativity and Quantum Cosmology (GRQC) field of research by analysing 38291 papers uploaded on the electronic archives arXiv.org from 2000 to 2012. We establish a map of the countries contributing to GRQC in 2012.

Cosmological Special Theory of Relativity, Cosmological Quantum Physics, Cosmological Uncertainty Principles, Cosmological General Theory of Relativity [PDF]
SSRN Electronic Journal, 2023 In cosmological special relativity theory, we study Maxwell equations, electromagnetic wave equations and functions. In the cosmological special theory of relativity, we study energy?momentum relations, the Klein-Gordon equation and wave functions. If we solve the Klein?Gordon equation, we obtain the Yukawa potential in the cosmological inertial frame.

ON THE RUNNING OF THE COSMOLOGICAL CONSTANT IN QUANTUM GENERAL RELATIVITY [PDF]
Modern Physics Letters A, 2010 We present arguments that show what the running of the cosmological constant means when quantum general relativity is formulated following the prescription developed by Feynman.

Hybrid Loop Quantum Cosmology: An Overview [PDF]
Frontiers in Astronomy and Space Sciences, 2021 Loop Quantum Gravity is a nonperturbative and background independent program for the quantization of General Relativity. Its underlying formalism has been applied successfully to the study of cosmological spacetimes, both to test the principles and ...

Running of the cosmological constant and estimate of its value in quantum general relativity [PDF]
Modern Physics Letters A, 2015 We present the connection between the running of the cosmological constant and the estimate of its value in the resummed quantum gravity (RQG) realization of quantum general relativity. We also address in this way some of the questions that have been raised concerning this latter generalization and application of the original prescription of Feynman ...
