Deformation quantization for fermionic fields
The deformation quantization of any Grassmann free field, or fermionic free field, in particular, the Dirac free field is discussed. Stratonovich-Weyl quantizer, Moyal product andWigner functionals are obtained for this field by deforming suitable Fermi oscillator variables. In additionthe propagato...

| Sumario: | The deformation quantization of any Grassmann free field, or fermionic free field, in particular, the Dirac free field is discussed. Stratonovich-Weyl quantizer, Moyal product andWigner functionals are obtained for this field by deforming suitable Fermi oscillator variables. In additionthe propagator of the Dirac field is computed in this context. |
