Vacuum Stress Tensor of a Scalar Field in a Rectangular Waveguide
R. B. Rodrigues, N. F. Svaiter, R. D. M. De Paola
Using the heat kernel method and the analytic continuation of the zeta function, we calculate the canonical and improved vacuum stress tensors, and ${Θ_{μν}(\ve…

A Rotating Vacuum and the Quantum Mach's Principle
R. D. M. De Paola, N. F. Svaiter
In this work we consider a quantum analog of Newton's bucket experiment in a flat spacetime: we take an Unruh-DeWitt detector in interaction with a real massless scalar field. We c…

Radiative processes for Rindler and accelerating observers and the stress-tensor detector
R. De Paola, N. F. Svaiter
We consider a monopole detector interacting with a massive scalar field. The radiative processes are discussed from the accelerated frame point of view. After this, we obtain the M…
