Description

A self-contained introduction to classical electron theory and non-relativistic quantum electrodynamics. This book provides a self-contained and systematic introduction to classical electron theory and non-relativistic quantum electrodynamics. It covers the interaction between charges and the Maxwell field, with emphasis on radiation phenomena and relaxation to the ground state, space-adiabatic limit, effective mass and g-factor and removal of the ultraviolet cut-off.

It covers the interaction between charges and the Maxwell field, with emphasis on radiation phenomena and relaxation to the ground state, space-adiabatic limit, effective mass and g-factor and removal of the ultraviolet cut-off. This book provides a self-contained and systematic introduction to classical electron theory and its quantization, non-relativistic quantum electrodynamics. The first half of the book covers the classical theory. It discusses the well-defined Abraham model of extended charges in interaction with the electromagnetic field, and gives a study of the effective dynamics of charges under the condition that, on the scale given by the size of the charge distribution, they are far apart and the applied potentials vary slowly. The second half covers the quantum theory, leading to a coherent presentation of non-relativistic quantum electrodynamics. Topics discussed include non-perturbative properties of the basic Hamiltonian, the structure of resonances, the relaxation to the ground state through emission of photons, the non-perturbative derivation of the g-factor of the electron and the stability of matter.

'… Herbert Spohn's book … covers both the classical and quantum theories of a charged particle coupled to its own field … One of the most useful resources in Spohn's book are the historical notes and literature reviews that are inserted at the end of each chapter. … I am grateful that the author made the effort to collect this information for the benefit of his readers.'
