    Quantization of Free Field: Dirac Field

    The canonical quantization of Spinor Field(Dirac Field). One can find that the usual quantization procedure(canonical commutation relationship) does not work for it, because it leads to the Hamiltonian with no lower bound. To quantize it correctly, we need modify it as the anti-commutation relationship, which means that Dirac particles are Fermions. Then we will computation of propagator and do some discussion. At last we will discuss the discrete symmetry of Dirac Field in Quantum Theory

    The canonical quantization of Real-valued Scalar Field(Klein Gordon Field). And computation of propagator and discussion, especially the causality property. At last we will discuss the discrete symmetry of Klein Gordon Field in Quantum Theory
