Closed-form expressions for smeared bi-distributions of a massless scalar field: non-perturbative and asymptotic results in relativistic quantum information
T. Rick Perche
Using spacetime Gaussian test functions, we find closed-form expressions for the smeared Wightman function, Feynman propagator, retarded and advanced Green's functions, causal prop…
Fully Relativistic Entanglement Harvesting
T. Rick Perche, José Polo-Gómez, Bruno de S. L. Torres +1
We study the protocol of entanglement harvesting when the particle detectors that harvest entanglement from the field are replaced by fully relativistic quantum field theories. We…
Ambient temperature versus ambient acceleration in the circular motion Unruh effect
Cameron R. D. Bunney, Leo Parry, T. Rick Perche +1
It is well known that the experience of a linearly accelerated observer with acceleration , interacting with a massless scalar field in its vacuum state in Minkowski space…
Particle Detectors from Localized Quantum Field Theories
T. Rick Perche, José Polo-Gómez, Bruno de S. L. Torres +1
We present a fully relativistic model for localized probes in quantum field theory. Furthermore, we show that it is possible to obtain particle detector models from localized quant…
Duality between amplitude and derivative coupled particle detectors in the limit of large energy gaps
T. Rick Perche, Matheus H. Zambianco
We present a duality between a particle detector model coupled to the amplitude of a scalar field and coupled to the field's derivative in the limit of large energy gaps. We show t…
Migrating Carrollian particles on magnetized black hole horizons
Jiri Bicak, David Kubiznak, T. Rick Perche
By considering a misaligned (asymptotically uniform) magnetic field in the background of a rotating black hole, we uncover a possibility for a highly non-trivial motion of Carrolli…
