Hubble tension problem encompassed by phase-space quantum cosmology
Alex E. Bernardini
The paper proposes a phase‑space quantum cosmology framework using Weyl–Wigner mechanics to derive quantum corrections to the Friedmann equation that can reduce the discrepancy bet…
On dark sector scalar field theories driven by cosmological -fields
Alex E. Bernardini, Orfeu Bertolami
The interplay of Hoyle-Narlikar (HN) creation field cosmology and scalar field models for the dark sector, including the generalized Chaplygin Gas (GCG), is investigated . Though o…
Toda-like Hamiltonian as a probe for quantized prey-predator dynamics
Alex E. Bernardini, Orfeu Bertolami
Phase-space features of a reduced version of the Toda-like Hamiltonian, , written in a form constrained by the condition $\partial^2 \mathcal{H} / \partial x \p…
Soft quantum back reaction to the Hubble tension: a smeared-out early time cosmological energy density
Alex E. Bernardini
A theoretical explanation for the so-called Hubble tension is provided within the framework of phase-space quantum mechanics extended to (quantum) cosmology. Following a descriptio…
Phase-space gaussian ensemble quantum camouflage
Alex E. Bernardini, Orfeu Bertolami
Extending the phase-space description of the Weyl-Wigner quantum mechanics to a subset of non-linear Hamiltonians in position and momentum, gaussian functions are identified as the…
Phase-space quantum distorted stability pattern for Aubry-André-Harper dynamics
Alex E. Bernardini, Orfeu Bertolami
Instability features associated to topological quantum domains which emerge from the Weyl-Wigner (WW) quantum phase-space description of Gaussian ensembles driven by Aubry-André-H…
