Description

The method proposed by K. Symanzik for constructing quantum field models in an inhomogeneous space-time is used to describe the interaction of the quantum electrodynamics (QED) fields with extended material objects. It is carried out within the framework of quantum field models in which the QED Lagrangian is modified according to the QED basic principles (locality, gauge invariance, renormalizability) and taking into account the properties of the material medium interacting with QED fields. Models with interactions of electromagnetic and Dirac fields with two-dimensional materials of flat, spherical and cylindrical shape are considered, and the specificity of their renormalization procedure is analyzed. The results obtained in such models for the Casimir effect, scattering processes and bound states are discussed.
