Thermofield dynamics and twisted Poincaré symmetry on Moyal space-time

preprint2010arXivOpen access

Abstract

On Moyal space-time, one can implement twisted Poincaré symmetry with the resultant modification of symmetrization and anti-symmetrization postulates for bosons and fermions. We develop the thermofield approach of Umezawa and Takahashi on such a spacetime preserving the twisted Poincaré symmetry of the underlying quantum field theory(qft). Implications of this twisted Poincaré symmetry for qft's at finite temperature are pointed out.
