The perturbed universe in the deformed algebra approach of Loop Quantum Cosmology
, 2016 Loop quantum cosmology is a tentative approach to model the universe down to the Planck era where quantum gravity settings are needed. The quantization of the universe as a dynamical space-time is inspired by Loop Quantum Gravity ideas. In addition, loop

Transport properties in the Horndeski holographic two-currents model
European Physical Journal C: Particles and Fields, 2023 The transport features of the holographic two-currents model are investigated in the Horndeski gravity framework. This system displays metallic or insulating characteristics depending on whether the Horndeski coupling parameter $$\gamma $$ γ is negative ...

Universe, 2022 The hybrid and the dressed metric formalisms for the study of primordial perturbations in Loop Quantum Cosmology lead to dynamical equations for the modes of these perturbations that are of a generalized harmonic-oscillator type, with a mass that depends

Observational Exclusion of a Consistent Quantum Cosmology Scenario
, 2015 It is often argued that inflation erases all the information about what took place before it started. Quantum gravity, relevant in the Planck era, seems therefore mostly impossible to probe with cosmological observations.

Higher-derivative Quantum Cosmology [PDF]
General Relativity and Gravitation, 2000 The quantum cosmology of a higher-derivative derivative gravity theory arising from the heterotic string effective action is reviewed. A new type of Wheeler-DeWitt equation is obtained when the dilaton is coupled to the quadratic curvature terms. Techniques for solving the Wheeler-DeWitt equation with appropriate boundary conditions shall be described,

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, EarlyView.ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Kant on Rational Reference: Theology as transcendental philosophy
European Journal of Philosophy, EarlyView.Abstract The Critical Kant famously held that our cognition requires intuition, or essentially singular representation. Kant is also often understood as taking a dismissive attitude toward his rationalist predecessors' accounts of how we cognize singulars or individuals.

Quantum out-of-equilibrium cosmology
European Physical Journal C: Particles and Fields, 2019 In this work, our prime focus is to study the one to one correspondence between the conduction phenomena in electrical wires with impurity and the scattering events responsible for particle production during stochastic inflation and reheating implemented

Classical and Quantum GravityAbstract There has been much discussion about the initial conditions of the early Universe in the context of quantum theory. In this paper, we construct the wave function and probability distribution by adopting the quantum version of the BPS equation instead of the usual Wheeler–DeWitt equation in a minisuperspace quantum cosmology with
