No classical particle limit for massless quanta
Riccardo Falcone, Simon Fuchs
We investigate whether relativistic massless classical particles may emerge as the classical limit of massless quanta. To address this question independently of any specific dynami…
Realistic prospects for testing a relativistic local quantum measurement inequality
Riccardo Falcone, Claudio Conti
We investigate the experimental prospects for testing a relativistic local quantum measurement inequality that quantifies the trade-off between vacuum insensitivity and responsiven…
An inequality for relativistic local quantum measurements
Riccardo Falcone, Claudio Conti
We investigate the trade-off between vacuum insensitivity and sensitivity to excitations in finite-size detectors, taking measurement locality as a fundamental constraint. We deriv…
Reeh-Schlieder approximation for coherent states
Riccardo Falcone, Claudio Conti
We present an explicit, fully local Reeh-Schlieder approximation scheme for coherent states of a free scalar field. For any bounded region , we construct a one-paramet…
Particle trajectories in light pulse spacetime
Riccardo Falcone, Claudio Conti
In our previous work (Phys. Rev. Research 7, 033079), we derived the metric tensor for cylindrically shaped pulses with uniform energy density. Building upon that framework, we der…
Black Hole Information From Non-vacuum Localised Quantum States
Ali Akil, Riccardo Falcone, Nicetu Tibau Vidal +1
We revisit Hawking's black hole radiation derivation, including the quantum state of the initial matter forming the black hole. We investigate how non-vacuum initial quantum states…
