Observations in quantum cosmology
Classical and Quantum Gravity, 2023 AbstractIn this review, we focus on whether a canonical quantization of general relativity can produce testable predictions for cosmology. In particular, we examine how this approach can be used to model the evolution of primordial perturbations.

Thermodynamics in Loop Quantum Cosmology
Advances in High Energy Physics, 2009 Loop quantum cosmology (LQC) is very powerful to deal with the behavior of early universe. Moreover, the effective loop quantum cosmology gives a successful description of the universe in the semiclassical region.

Correspondence between dark energy quantum cosmology and Maxwell equations
European Physical Journal C: Particles and Fields, 2019 A Friedmann–Robertson–Walker cosmology with dark energy can be modelled using a quintessence field. That system is equivalent to a relativistic particle moving on a two-dimensional conformal spacetime.

Hořava-Lifshitz Scalar Field Cosmology: Classical and Quantum Viewpoints
Advances in High Energy Physics, 2021 In this paper, we study a projectable Hořava-Lifshitz cosmology without the detailed balance condition minimally coupled to a nonlinear self-coupling scalar field.

Quantum cosmology and tachyons [PDF]
Fortschritte der Physik, 2008 AbstractWe discuss the relevance of the classical and quantum rolling tachyons inflation in the frame of the standard, p‐adic and adelic minisuperspace quantum cosmology. The field theory of tachyon matter proposed by Sen in a zero‐dimensional version suggested by Kar leads to a model of a particle moving in a constant external field with quadratic ...

Polymer Dynamics of Isotropic Universe in Ashtekar and in Volume Variables
Universe, 2022 We analyze the semiclassical and quantum polymer dynamics of the isotropic Universe in terms of both the standard Ashtekar-Barbero-Immirzi connection and its conjugate momentum and also of the new generalized coordinate conjugate to the Universe volume ...
