Remarks on vacuum fluctuations around a spinning cosmic string

V. A. De Lorenci, E. S. Moreira

We apply the point-splitting method to investigate vacuum fluctuations in the nonglobally hyperbolic background of a spinning cosmic string. Implementing renormalization by removin…

Thermal fluctuations of a quantized massive scalar field in Rindler background

R. Medina, E. S. Moreira, jr

Thermal fluctuations for a massive scalar field in the Rindler wedge are obtained by applying the point-splitting procedure to the zero temperature Feynman propagator in a conical…

Spillover and diffraction sidelobe contamination in a double-shielded experiment for mapping Galactic synchrotron emission

C. Tello, T. Villela, G. F. Smoot +6

We have analyzed observations from a radioastronomical experiment to survey the sky at decimetric wavelengths along with feed pattern measurements in order to account for the level…

Light propagation in non linear electrodynamics

V. A. De Lorenci, R. Klippert, M. Novello +1

Working on the approximation of low frequency, we present the light cone conditions for a class of theories constructed with the two gauge invariants of the Maxwell field without m…

The Rotating Detector and Vacuum Fluctuations

V. A. De Lorenci, R. D. M. De Paola, N. F. Svaiter

In this work we compare the quantization of a massless scalar field in an inertial frame with the quantization in a rotating frame. We used the Trocheries-Takeno mapping to relate…
