Spin-12 Particles in Phase Space: Casimir Effect and Stefan-Boltzmann Law at Finite Temperature

الملخص EN

The Dirac field, spin 1/2 particles, is investigated in phase space.

The Dirac propagator is defined.

The Thermo Field Dynamics (TFD) formalism is used to introduce finite temperature.

The energy-momentum tensor is calculated at finite temperature.

The Stefan-Boltzmann law is established, and the Casimir effect is calculated for the Dirac field in phase space at zero and finite temperature.

A comparative analysis with these results in standard quantum mechanics space is realized.
