| contents | The Casimir Effect: Some Aspects Carlos Farina Física, Astronomía y Matemáticas Casimir effect Quantum field theory We start this paper with a historical survey of the Casimir effect, showing that its origin is related to experimentson colloidal chemistry. We present two methods of computing Casimir forces, namely: the globalmethod introduced by Casimir, based on the idea of zero-point energy of the quantum electromagnetic field, anda local one, which requires the computation of the energy-momentum stress tensor of the corresponding field.As explicit examples, we calculate the (standard) Casimir forces between two parallel and perfectly conductingplates and discuss the more involved problem of a scalar field submitted to Robin boundary conditions at twoparallel plates. A few comments are made about recent experiments that undoubtedly confirm the existence ofthis effect. Finally, we briefly discuss a few topics which are either elaborations of the Casimir effect or topicsthat are related in some way to this effect as, for example, the influence of a magnetic field on the Casimir effectof charged fields, magnetic properties of a confined vacuum and radiation reaction forces on non-relativisticmoving boundaries. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436606 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.4A Vol.36 |
