Gibbs average in the functional formulation of quantum field theory

A new formulation of the Euclidean functional approach to quantum field theory is proposed. It is based on functional integration over a Gibbs ensemble. This automatically ensures invariance with respect to general field transformations. The new momenta conjugate to the field variables perform natur...

description A new formulation of the Euclidean functional approach to quantum field theory is proposed. It is based on functional integration over a Gibbs ensemble. This automatically ensures invariance with respect to general field transformations. The new momenta conjugate to the field variables perform naturally the role of the ghost field required by the general consistency of the theory. (5 refs).
