Gupta-Bleuler quantization for massive and massless free vector fields
It is shown that the usual quantum field theory leads to an ultraviolet divergence in the vacuum energies and an infrared divergence in the two-point functions of the massive and massless vector fields. Using a new method of quantization it is shown that the vacuum energies converge, and the normal ordering procedure is not necessary. Also the propagators are calculated, which are automatically...
متن کاملSupersymmetric Gupta-Bleuler Quantisation
We formulate the Gupta-Bleuler canonical, covariant and gauge invariant supersymmetric quantization of the supersymmetric (massless) vector field. Our main tool is the recently introduced HilbertKrein structure of the N = 1 superspace.
متن کاملOn the complex structure in the Gupta–Bleuler quantization method
We examine the general conditions for the existence of the complex structure intrinsic in the Gupta-Bleuler quantization method for the specific case of mixed first and second class fermionic constraints in an arbitrary space-time dimension. The cases d = 3 and 10 are shown to be of prime importance. The explicit solution for d = 10 is presented.
متن کاملHamiltonian quantization of effective Lagrangians with massive vector fields.
Effective Lagrangians containing arbitrary interactions of massive vector fields are quantized within the Hamiltonian path integral formalism. It is proven that correct Hamiltonian quantization of these models yields the same result as naive Lagrangian quantization (Matthews’s theorem). This theorem holds for models without gauge freedom as well as for (linearly or nonlinearly realized) spontan...
متن کاملGupta-Bleuler quantization of the Maxwell field in globally hyperbolic space-times
We give a complete framework for the Gupta-Bleuler quantization of the free electromagnetic field on globally hyperbolic space-times. We describe oneparticle structures that give rise to states satisfying the microlocal spectrum condition. The field algebra in the so-called Gupta-Bleuler representations satisfies the time-slice axiom, and the corresponding vacuum states satisfy the microlocal s...
