Tachyonic modes as a resonant system in weakly curved stellar spacetimes
Bruno S. Felipe, Maurício Richartz
A real scalar field nonminimally coupled to the curvature of an astrophysical object can develop an effective potential that supports, alongside stable oscillatory solutions, a set…
Unstable mode and the Unruh-DeWitt detector
Bruno S. Felipe, João P. M. Pitelli
We investigate the quantization of a single unstable mode in a real scalar field subject to a Robin boundary condition in (1+1)-dimensional half-Minkowski spacetime. The instabilit…
Quantum superposition of boundary condition in
João P. M. Pitelli, Bruno S. Felipe, Claudio Dappiaggi +1
We explore the quantum superposition of boundary conditions in the context of the Poincaré patch of the two-dimensional Anti-de Sitter space (). Focusing on Robin…
Quantum Approach to Bound States in Field Theory
Bruno S. Felipe, João P. M. Pitelli
It is well known that (possibly non-unique) suitable field dynamics can be prescribed in spacetimes with timelike boundaries by means of appropriate boundary conditions. In Ref. [J…
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…
