States and Observables in Hamiltonian Semiclassical Scalar Electrodynamics
O. Yu. Shvedov
The main notions of semiclassical scalar electrodynamics in different gauges (Hamiltonian, Couloumb, Lorentz) are discussed. These are semiclassical states, Poincare transformation…
An Axiomatic Approach to Semiclassical Field Perturbation Theory
O. Yu. Shvedov
Semiclassical perturbation theory is investigated within the framework of axiomatic field theory. Axioms of perturbation semiclassical theory are formulated. Their correspondence w…
States and Observables in Semiclassical Field Theory: a Manifestly Covariant Approach
O. Yu. Shvedov
A manifestly covariant formulation of quantum field Maslov complex-WKB theory (semiclassical field theory) is investigated for the case of scalar field. The main object of the theo…
A Third-Quantized Approach to the Large-N Field Models
V. P. Maslov, O. Yu. Shvedov
Large-N field systems are considered from an unusual point of view. The Hamiltonian is presented in a third-quantized form analogously to the second-quantized formulation of the qu…
Renormalization of the Semiclassical Hamiltonian Field Theory
V. P. Maslov, O. Yu. Shvedov
The Hamiltonian approach to the quantum field theory is considered. Since there are additional difficulties such as the Haag theorem and Stueckelberg divergences, renormalization o…
