The multimode nature of spacetime entanglement in QFT

Ivan Agullo, Béatrice Bonga, Eduardo Martín-Martínez +5

We demonstrate the presence of multimode entanglement in the vacuum state of a free, massless scalar quantum field in four-dimensional flat spacetime between two sets of field mode…

Measurements in QFT: Weakly coupled local particle detectors and entanglement harvesting

Daniel Grimmer, Bruno de S. L. Torres, Eduardo Martín-Martínez

We present a comparison of the AQFT-based Fewster-Verch framework with the Unruh-DeWitt particle detector models commonly employed in relativistic quantum information and QFT in cu…

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…
