Thermofield dynamics and twisted Poincaré symmetry on Moyal space-time (1006.1528v5)
Published 8 Jun 2010 in hep-th and hep-ph
Abstract: On Moyal space-time, one can implement twisted Poincar\'e 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 Poincar\'e symmetry of the underlying quantum field theory(qft). Implications of this twisted Poincar\'e symmetry for qft's at finite temperature are pointed out.
