Field Theory Reformulated without Self-energy Parts. the Dressing Operator
The reformulation of field theory for avoiding self-energy parts in the dynamical evolution has been applied successfully in the framework of the Lee model,[1] enabling a kinetic extension of the description. The basic ingredient is the recognition of these self-energy parts.[2] The original reversible description is embedded in the new one and appears now as a restricted class of initial condi...
متن کاملField Theory reformulated without self - energy parts . Classical electrodynamics
A manifestly gauge-invariant hamiltonian formulation [1] of classical electrodynamics has been shown to be relativistic invariant by the construction of the generators of the Poincare Lie algebra. The original formulation in terms of reduced distribution functions for the particles is applied here to the case of two charges interacting through the classical electrodynamical field. A reduced des...

متن کاملRenormalization and dressing in quantum field theory
We illustrate the mass and charge renormalization procedures in quantum field theory using, as an example, a simple model of interacting electrons and photons. It is shown how addition of infinite renormalization counterterms to the Hamiltonian helps to obtain finite and accurate results for the S-matrix. In order to remove the ultraviolet divergences from the Hamiltonian, we apply the Greenber...
متن کاملA Field Theory for the Read Operator
We introduce a new field theory for studying quantum Hall systems. The quantum field is a modified version of the bosonic operator introduced by Read. In contrast to Read’s original work we do not work in the lowest Landau level alone, and this leads to a much simpler formalism. We identify an appropriate canonical conjugate field, and write a Hamiltonian that governs the exact dynamics of our ...
