Thermo Field Dynamics and quantum algebras

High Energy Physics - Theory 2009-10-31 v1

Abstract

The algebraic structure of Thermo Field Dynamics lies in the qq-deformation of the algebra of creation and annihilation operators. Doubling of the degrees of freedom, tilde-conjugation rules, and Bogoliubov transformation for bosons and fermions are recognized as algebraic properties of hq(1)h_{q}(1) and of hq(11)h_{q}(1|1), respectively.
