Abstract

The real-time operator formalism for thermal quantum field theories, thermofield dynamics, is formulated in terms of a path-integral approach in non-commutative spaces. As an application, the two-point function for a thermal non-commutative λϕ4\lambda \phi^4 theory is derived at the one-loop level. The effect of temperature and the non-commutative parameter, competing with one another, is analyzed.
