On Normal ordering and Canonical transformations in Thermal Field Theory
arXiv:hep-ph/9706549 · doi:10.1088/0305-4470/32/7/009
Abstract
We look at a real scalar field in thermal equilibrium in the context of the new normal ordering and field split defined by Evans and Steer. We show that the field split defines a natural canonical transformation, but that this transformation differs from others known in thermal field theory.
