Inflationary magnetogenesis in Proca electrodynamics with Schwinger particle production

Mattia Dubbini, Orlando Luongo

We investigate inflationary magnetogenesis with massive vector fields, including charged scalar particle production via the Schwinger effect and its backreaction on the background…

Causal structure and optical signatures of rotating power law Kalb-Ramond geometry

Hassan Hassanabadi, Orlando Luongo

We investigate a stationary and axisymmetric power law Kalb-Ramond geometry, obtained as a rotating extension of the asymptotically flat static solution. We reconstruct the exact i…

Cosmological horizon thermodynamics in Gauss-Bonnet quasi-dilaton Massive Gravity

Sobhan Kazempour, Orlando Luongo, Sabahat +2

We investigate the thermodynamic properties of the cosmological apparent horizon in Gauss-Bonnet quasi-dilaton massive gravity. We derive the modified Friedmann equations and refor…

Optical and thermodynamic properties of Kerr-Bertotti-Robinson black holes

Hassan Hassanabadi, Michael R. R. Good, Soroush Zare +2

We investigate the thermodynamic and optical properties of Kerr--Bertotti--Robinson black holes, namely rotating black holes immersed in an external Bertotti--Robinson electromagne…

Entanglement generation from gravitationally produced massless vector particles during inflation

Alessio Belfiglio, Mattia Dubbini, Orlando Luongo

We study the gravitational production of spectator massless vector particles in a single-field inflationary scenario, and the related entanglement generation across the Hubble hori…
