Action-level characterization of gravitational-wave propagation in dynamical Barbero--Immirzi gravity
Zhi-Fu Gao, Hui Wang, Luiz Carlos Garcia de Andrade +3
We investigate which operators in first-order dynamical Barbero--Immirzi (BI) gravity control cosmological tensor propagation at the action level. Within a bosonic, two-derivative,…
Dynamical Barbero--Immirzi field coupled to quintessence: gravitational-wave propagation constraints and next-generation forecasts
Zhi-Fu Gao, Hui Wang, Luiz Carlos Garcia de Andrade +3
We investigate the imprints of a dynamical Barbero--Immirzi (BI) field coupled to a quintessence scalar field on gravitational-wave (GW) propagation. In the framework of…
Is there a chiral dark dynamo in the universe induced by quantum correction, Nieh-Yan gravity and Barbero-Immirzi field?
Zhi Fu Gao, Biao Peng Li, L. C. Garcia de Andrade
Bombagcino investigated the role of Immirzi parameter when promoted to a field in Einstein-Cartan-Holst black hole and they found that the Immirzi field acts similar to the axion f…
Axion-photon-mixing dark matter conversion mediated by torsion mass constrained by the Barbero-Immirzi parameter
Zhi-Fu Gao, Luiz C. Garcia de Andrade
In the Standard Model\,(SM) of particle physics, photon-torsion mixing is extended to include the Einstein-Cartan portal to dark-photon-axion-torsion mixing beyond the Standard Mod…
Chern-Simmons electrodynamics and torsion dark matter axions
Zhifu Gao, Luiz C. Garcia de Andrade
In this paper, we delve into the influence of torsion axial pseudo vector on dark photons in an axion torsionic background, as investigated previously by Duncan et al[ Nucl Phys B…
