A pedagogical introduction to Bell’s inequality in Quantum Mechanics is presented. Several examples, ranging from spin 1/2 to coherent and squeezed states are worked out. The generalization to Mermin’s inequalities and to GHZ states is also outli

A relativistic Quantum Field Theory framework is devised for Mermin's inequalities. By employing smeared Dirac spinor fields, we are able to introduce unitary operators which create, out of the Minkowski vacuum |0〉, GHZ-type states. In this way, we

We provide a short discussion of the dimension two condensate and its influence on the infrared behaviour of the gluon propagator in the Landau gauge. Simultaneously, we pay attention to the issue of Gribov copies in the Landau gauge. We also briefly

A study of the Bell-CHSH inequality in gauge field theories is presented. By using the Kugo-Ojima analysis of the BRST charge cohomology in Fock space, the Bell-CHSH inequality is formulated in a manifestly BRST invariant way. The examples of the fre

O comportamento infra-vermelho dos propagadores de glúons e de ghosts é de fundamental importância para o entendimento do limite de baixas energias da cromodinâmica quântica (QCD), especialmente no que diz respeito ao problema do confinamento de

Neste trabalho propomos uma generalização do procedimento de Resgularização Implícita para ordens além da primeira ordem na expansão em loops, no contexto de tórias de calibre. Nesta extensão do procedimento, as divergências ultra-violeta s

Aplicamos a Técnica de Regularização Implícita (RI) a uma teoria de calibre não-abeliana e a uma teoria supersimétrica. Na primeira parte mostramos que a IR preserva a simetria de calibre afirmada nas relações entre as contantes de renormaliz
