Thermal effects on a global monopole with Robin boundary conditions
Lissa de Souza Campos, João Paulo M. Pitelli
Within quantum field theory on a global monopole spacetime, we study thermal effects on a naked singularity and its relation with boundary conditions. We first obtain the two-point…
Unruh-DeWitt detector in
João Paulo M. Pitelli, Bruno S. Felipe, Ricardo A. Mosna
We find the response function and the transition rate for an Unruh-DeWitt detector interacting with a conformal scalar field in global two-dimensional anti--de Sitter (AdS) spaceti…
Analogue models for Schwarzschild and Reissner-Nordström spacetimes
Christyan C. de Oliveira, Ricardo A. Mosna, João Paulo M. Pitelli +1
We present analogue models for the Schwarzschild and Reissner-Nordström (RN) spacetimes based on unidirectional hydrodynamic flows. We show that, with appropriate coordinate transf…
An angular momentum based graviton detector
J. P. M. Pitelli, T. Rick Perche
We show that gravitons with energy , where is the energy gap a localized non-relativistic system, can be detected by finite-time interactions with a detector. Our detector…
