Ergoregion instability of a rotating quantum system
Leandro A. Oliveira, Luis J. Garay, Luís C. B. Crispino
Using the analogy between acoustic perturbations in an ideal fluid and the description of a Klein-Gordon scalar field in a curved spacetime, we study the quasinormal modes of a qua…
Direct measurement of the two-point function in quantum fields
Jose de Ramon, Luis J. Garay, Eduardo Martin-Martinez
We analyze fast interaction cycles in bipartite quantum systems, showing that the statistics in one of the parties (the detector) can be used to determine the two-point correlator…
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…
