Thermofield dynamics and twisted Poincaré symmetry on Moyal space-time
arXiv:1006.1528 · doi:10.1103/PhysRevD.82.105025
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.
