A path integral formulation for particle detectors: the Unruh-DeWitt model as a line defect
I. M. Burbano, T. Rick Perche, Bruno de S. L. Torres
Particle detectors are an ubiquitous tool for probing quantum fields in the context of relativistic quantum information (RQI). We formulate the Unruh-DeWitt (UDW) particle detector…
A Wavefunction Description for a Localized Quantum Particle in Curved Spacetimes
T. Rick Perche, Jonas Neuser
We reduce Dirac's spinor formalism for a spin 1/2 particle to a complex wavefunction description in curved spacetimes. We consider a localized fermionic particle in curved spacetim…
Taub-NUT solutions in conformal electrodynamics
Alvaro Ballon Bordo, David Kubiznak, Tales Rick Perche
We construct a novel charged Taub-NUT spacetime, providing a first non-trivial example of a self-gravitating solution to the recently proposed ModMax theory, the most general (1-pa…
Neutrino flavor oscillations without flavor states
Bruno de S. L. Torres, T. Rick Perche, André G. S. Landulfo +1
We analyze the problem of neutrino oscillations via a fermionic particle detector model inspired by the physics of the Fermi theory of weak interactions. The model naturally leads…
Broken covariance of particle detector models in relativistic quantum information
Eduardo Martín-Martínez, T. Rick Perche, Bruno de S. L. Torres
We show that the predictions of spatially smeared particle detectors coupled to quantum fields are not generally covariant outside the pointlike limit. This lack of covariance mani…
Particle detectors as witnesses for quantum gravity
Rémi Faure, T. Rick Perche, Bruno de S. L. Torres
We present a model for the coupling of non-relativistic quantum systems with a linearized gravitational field from a Lagrangian formulation. The coupling strongly resembles the lig…
Conformally Coupled Scalar in Rotating Black Hole Spacetimes
Finnian Gray, Ian Holst, David Kubiznak +3
We demonstrate separability of conformally coupled scalar field equation in general (off-shell) Kerr-NUT-AdS spacetimes in all dimensions. The separability is intrinsically charact…
