O presente trabalho determina a pressão de Casimir seguindo as ideias da Eletrodinâmica Quântica Finita (Finite QED), i.e., construímos uma expressão para o tensor energia-momento (E-M) do campo de radiação quantizado de maneira a eliminar qualquer procedimento posterior de renormalização na obtenção de resultados finitos para os observáveis físicos, em particular, para a energia e o momento. O ponto de partida para este desenvolvimento é uma proposta de produto de operadores a ser utilizada na construção de observáveis, para os quais as medidas físicas sejam sempre resultados finitos. Com esta motivação, desenvolvemos o cálculo da pressão de Casimir no calibre de Coulomb considerando dois tipos de condições de fronteira: a de Dirichlet e a de Neumann.Downloads
