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…
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…
