Abstract
The process of radiation by a uniformly accelerated charge, although both fundamental and elementary, has long been a subject of controversy. The conceptual issues are intensified when gravity is brought into the picture, and they have come even more to the fore now that a related effect in quantum theory (named after Unruh), which usually deals with a neutral system with internal degrees of freedom rather than a charge, has attracted sustained attention. The crucial (and counter-intuitive) point is that the acceleration of the observer, or measuring instrument, is also relevant. The Pls believe that they are well qualified to bring clarity into this subject by both original theoretical research and review of the large literature of these topics. Besides cleaning up loopholes in basic physics, the project may have implications for two major experimental projects: LIGO (for the detection of gravitational waves) and DUNE (for the study of neutrino mixing). More immediately, the past and present work of the Brazilian team can contribute to clarification of theoretical predictions by members of the TAMU quantum optics group concerning the behavior of atoms falling into a black hole; and TAMU atomic experimentalists can offer technical advice on the Brazilian group's proposal for observing the Unruh effect using classical electrodynamics. Thus the Sao Paulo and TAMU teams will profit from each other's expertise and, we hope, seed a long-standing collaboration. (AU)
