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…
Virasoro hair and entropy for axisymmetric Killing horizons
Lin-Qing Chen, Wan Zhen Chua, Shuwei Liu +2
We show that the gravitational phase space for the near-horizon region of a bifurcate, axisymmetric Killing horizon in any dimension admits a 2D conformal symmetry algebra with cen…
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…
