Study on Inertia as a Gravity Induced Property of Mass, in an Infinite Hubble Expanding Universe by Jeroen van Engelshoven

“…Then, we propose a generalization of the linearized theory and evaluate the Hubble expanding universe. It is shown that the gravitational impact of an infinite expanding universe creates finite inertia, according to . …”

Dark Energy from Cosmological Energy Conservation by Manuel Uruena Palomo

“…A derivation of its value is presented under the assumption that energy lost due to cosmic redshift is fully responsible for the energy gained by the cosmological constant in the expanding universe. This unknown nonlocal mechanism of energy conservation on the cosmic scale could explain dark energy and hint at a property of a theory of quantum gravity.…”

Coupling q-Deformed Dark Energy to Dark Matter by Emre Dil

“…We propose a novel coupled dark energy model which is assumed to occur as a q-deformed scalar field and investigate whether it will provide an expanding universe phase. We consider the q-deformed dark energy as coupled to dark matter inhomogeneities. …”

Probing the curvature of the cosmos from quantum entanglement due to gravity by Suddhasattwa Brahma, Abhinove N. Seenivasan

“…In this paper, we generalize this to imagine two idealized massive oscillators, in their ground state, which get entangled due to gravity in an expanding universe, and find that the curvature of the background spacetime leaves its imprints on the resulting entanglement profile. …”

Cosmological entanglement of initial multipartite states by Xiao-Ying Jiang, Xiao-Li Huang, Shu-Min Wu

“…Abstract In this study, we investigate the intricate interplay between the entanglement entropy of initial multipartite states characterized by a nonzero particle number q and the dynamics of an expanding universe. Our analysis demonstrates that spacetime expansion significantly enhances the particle production rate associated with such states, yielding an amplification factor of $$q + 1 + \frac{q}{|\beta |^2}$$ q + 1 + q | β | 2 compared to the vacuum scenario. …”

Deformation quantization in FLRW geometries by Alfonso F. Bobadilla, Jose A. R. Cembranos

“…By employing a perturbative approach, we elaborate on the case of a particle described by a spherically symmetric Wigner distribution and explore the implications for phase-space dynamics in expanding universes. Our findings provide new insights into the interplay between quantum mechanics, phase-space formulations, and cosmological expansion, highlighting the importance of deformation quantization techniques for understanding quantum systems in curved spacetime.…”

Fermionic steering in multi-event horizon spacetime by Shu-Min Wu, Jin-Xuan Li, Yu-Xuan Wang, Si-Han Shang, Jianbo Lu

Polarization Properties of the Electromagnetic Response to High-frequency Gravitational Wave by Jian-Kang Li, Wei Hong, Tong-Jie Zhang

“…The conversion probability between GWs and EMWs can be enhanced by inhomogeneities in the electron density and magnetic field within the magnetized plasma of both the Milky Way (MW) and the intergalactic medium in the expanding Universe. Polarized GWs can induce polarized EMWs, and the polarization properties of these EMWs can be altered by Faraday rotation as they propagate through magnetized plasma. …”
