Clothed particle operators in simple models of quantum field theory
SummaryThe idea of using clothed operators in the quantum theory of fields, i.e. operators which create and annihilate one particle eigenstates of the total Hamiltonian, is examined. In cut-offExpand

Generalized Bose Operators in the Fock Space of a Single Bose Operator
Generalized Bose operators b which reduce by two the number of quanta of a Bose operator a are studied in the Fock space of a. All representations of the b's as normal‐ordered (infinite degree) powerExpand
