Phase operator for one-photon quantized field
Based on the quantization of one-photon electromagnetic field described in terms of the Riemann-Silberstein complex vector F, we construct the eigenvector set of F, this set is orthonormal and complete, with which we introduce the phase operator for one-photon state. It is shown that this phase operator manifestly exhibits phase behaviour.
متن کاملOn momentum operator in quantum field theory
The interrelations between the two definitions of momentum operator, via the canonical energy-momentum tensorial operator and as translation operator (on the operator space), are studied in quantum field theory. These definitions give rise to similar but, generally, different momentum operators, each of them having its own place in the theory. Some speculations on the relations between quantum ...
متن کاملInstanton Calculus and Loop Operator in Supersymmetric Gauge Theory
We compute one-point function of the glueball loop operator in the maximally confining phase of supersymmetric gauge theory using instanton calculus. In the maximally confining phase the residual symmetry is the diagonal U(1) subgroup and the localization formula implies that the chiral correlation functions are the sum of the contributions from each fixed point labeled by the Young diagram. Th...
متن کاملParent field theory and unfolding in BRST first-quantized terms
For free field theories associated with BRST first-quantized gauge systems, we identify auxiliary fields and pure gauge variables already on the first-quantized level as the fields associated with algebraically contractible pairs for the BRST operator. Locality of the field theory is taken into account by separating the space–time degrees of freedom from the internal ones. A standard extension ...
متن کاملNeutrix Calculus and Finite Quantum Field Theory
In general, quantum field theories (QFT) require regularizations and infinite renormalizations due to ultraviolet divergences in their loop calculations. Furthermore, perturbation series in theories like QED are not convergent series, but are asymptotic series. We apply neutrix calculus, developed in connection with asymptotic series and divergent integrals, to QFT, obtaining finite renormaliza...
