TY - JOUR AU - Pottel, Steffen AU - Sibold, Klaus T1 - Conjugate variables in quantum field theory and a refinement of Pauli’s theorem JF - Physical Review D IS - 6: ID 065008 VL - 94 PY - 2016 AB - For the case of spin zero, we construct conjugate pairs of operators on Fock space. On states multiplied by polarization vectors, coordinate operators Q conjugate to the momentum operators P exist. In the massive case the notion of interest is derived from a geometrical quantity, the massless case is realized by taking the limit m2→0 on the one hand, on the other, starting with m2=0 directly, from conformal transformations. The norm problem of the states on which the Q’s act is crucial: the states determine eventually how many independent conjugate pairs exist. It is intriguing that (light-) wedge variables and, hence, the wedge-local case seem to be preferred. TS - CrossRef DO - 10.1103/PhysRevD.94.065008 M4 - Citavi ER -
