A estrutura algébrica da dinâmica de campos térmicos, o formalismo da teoria quântica de campos à temperatura finita e a tempo real, são usados para o estudo do estado composto pela superposição de um estado número de Fock, |n >, com um estado coerente, | \alpha >. A análise dos efeitos da temperatura é realizada considerando a matriz densidade e a função de Wigner. Para tal propósito, vamos considerar a duplicação do estado original com o estado de vácuo do espaço dual.Downloads
