| contents | Scalar Source in Circular Motion Interacting with Massive Klein-Gordon Field in Minkowski Spacetime Luís C. B. Crispino Damião P. Meira Filho Física, Astronomía y Matemáticas We analyze the scalar radiation emitted by a source in uniform circular motion in Minkowski spacetimeinteracting with a massive Klein-Gordon field. We assume the source rotating around a central object due to aNewtonian force. By considering the canonical quantization of this field, we use perturbation theory to computethe radiation emitted at the tree level. Regarding the initial state of the field as being the Minkowski vacuum, wecompute the emission amplitude for the rotating source, assuming it as being minimally coupled to the massiveKlein-Gordon field. We then compute the power emitted by the swirling source as a function of its angularvelocity, as measured by asymptotic static observers. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435718 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4B Vol.35 |
