| Resumo | |
We propose a model for a finite-size particle detector, which allows us to derive its stress-energy tensor. This tensor is obtained from a covariant Lagrangian that describes not only the quantum field that models the detector, phi(D), but also the systems responsible for its localization: a complex scalar field psi(C) and a perfect fluid. The local interaction between the detector and the complex field ensures the square integrability of the detector modes, while the fluid serves to define the spatial profile of psi(C), localizing it in space. We then demonstrate that, under very general conditions, the resulting energy tensor-incorporating all components of the system-is physically reasonable and satisfies the energy conditions. (AU) | |
