Comparing geometric and gravitational particle production in Jordan and Einstein frames
Alessio Belfiglio, Orlando Luongo, Tommaso Mengoni
We explore cosmological particle production associated with inflationary fluctuations by comparing gravitational and geometric mechanisms, within a non-minimal Yukawa-like coupling…
Horizon entanglement area law from regular black hole thermodynamics
Alessio Belfiglio, S. Mahesh Chandran, Orlando Luongo +1
We investigate the thermodynamics of regular black hole configurations via quantum analogs of entropy and energy -- namely, the entanglement entropy and entanglement energy -- near…
Entanglement entropy in quantum black holes
Alessio Belfiglio, Orlando Luongo, Stefano Mancini +1
We discuss the entanglement entropy for a massive Klein-Gordon field in two Schwarzschild-like quantum black hole spacetimes, also including a nonminimal coupling term with the bac…
Production of ultralight dark matter from inflationary spectator fields
Alessio Belfiglio, Orlando Luongo
We investigate inflationary particle production associated with a spectator ultralight scalar field, which has been recently proposed as a plausible dark matter candidate. In this…
