Covariant non-perturbative pointer variables for quantum fields
Alejandro Blanco Sánchez, Luis J. Garay, Jose de Ramón
We describe the dynamics of a detector modeled by a harmonic oscillator coupled with an otherwise free quantum field in a curved spacetime in terms of covariant equations of motion…
Relativistic causality in particle detector models: Faster-than-light signalling and "Impossible measurements"
José de Ramón, Maria Papageorgiou, Eduardo Martín-Martínez
We analyze potential violations of causality in Unruh DeWitt-type detector models in relativistic quantum information. We proceed by first studying the relation between faster-than…
The Unruh effect without thermality
Raul Carballo-Rubio, Luis J. Garay, Eduardo Martin-Martinez +1
We show that uniformly accelerated detectors can display genuinely thermal features even if the Kubo-Martin-Schwinger (KMS) condition fails to hold. These features include satisfyi…
