A relativistic QFT description for the interaction of a spin with a magnetic field
Ruhi Shah, Eduardo Martín-Martínez, T. Rick Perche
We analyze how non-relativistic effective models for the magnetic coupling of a spin to the electromagnetic field (proportional to ) emerge…
The multimode nature of spacetime entanglement in QFT
Ivan Agullo, Béatrice Bonga, Eduardo Martín-Martínez +5
We demonstrate the presence of multimode entanglement in the vacuum state of a free, massless scalar quantum field in four-dimensional flat spacetime between two sets of field mode…
Reply to Comment on "No Black Holes from Light" [arXiv:2408.06714]
Álvaro Álvarez-Domínguez, Luis J. Garay, Eduardo Martín-Martínez +1
We discuss how the comment by A. Loeb [arXiv:2408.06714] has no bearing on the results of Phys. Rev. Lett. 133, 041401 (2024) [arXiv:2405.02389].
Derivative coupling enables genuine entanglement harvesting in causal communication
Adam Teixidó-Bonfill, Eduardo Martín-Martínez
We show that particle detectors coupled to a massless quantum field through its derivative can genuinely harvest entanglement form the field even when they are in causal contact in…
