Quantum Gravity Effects in Cosmology
EPJ Web of Conferences, 2018 Within the geometrodynamic approach to quantum cosmology, we studied the quantum gravity effects in cosmology. The Gibbons-Hawking temperature is corrected by quantum gravity due to spacetime fluctuations and the power spectrum as well as any probe field

Effective Field Theory of Loop Quantum Cosmology
Universe, 2019 Quantum cosmology is traditionally formulated in a minisuperspace setting, implicitly averaging fields over space to obtain homogeneous models. For universal reasons related to the uncertainty principle, quantum corrections then depend on the size of the

On the holographic basis of loop quantum cosmology
European Physical Journal C: Particles and Fields, 2018 In this work, we obtain the loop quantum cosmology dynamical equations, plus a positive cosmological constant, from the Bekenstein–Hawking entropy-area relation given by Loop Quantum Black Holes, by the use of the Jacobson formalism (Phys Rev Lett 75 ...

Pytanie o jedność nauki na przykładzie kosmologii antropicznej
Studia Philosophiae Christianae, 2023 Given the ongoing process of the differentiation of sciences, it is worth posing a question about the possibility of them being integrated. This matter will be explored with reference to anthropic cosmology.

On Under-determination in Cosmology [PDF]
, 2012 I discuss how modern cosmology illustrates under-determination of theoretical hypotheses by data, in ways that are different from most philosophical discussions.

Relational Quantum Cosmology [PDF]
, 2015 The application of quantum theory to cosmology raises a number of conceptual questions, such as the role of the quantum-mechanical notion of “observer” or the absence of a time variable in the Wheeler-DeWitt equation.

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.
