Response 4-tensors, the disturbance at earlier times, .′ < ., and other positions, .′ ≠ .. In describing such a response it is appropriate to Fourier transform so that both the disturbance and the response are regarded as functions of frequency, ., and wavevector, .. A variety of quantities may be chosen to describe t

Particle and wave subsystems,edium. The reinterpretation of a collection of individual particles and the electromagnetic field as a collective medium requires a formal rearrangement of the ‘bare’ particles and electromagnetic field into a background system of ‘dressed’ particles, sometimes called quasiparticles, and a ‘self-con

Classical plasmadynamics,vewave interactions in plasmas. A single-particle approach is usually used in treating spontaneous emission, and absorption may be treated either using a collective-medium approach, with dissipation included in the anithermitian part of the response tensor, or by relating absorption to emission.

Quantum field theory,e fields. In the absence of any interactions, the fields are defined by their Lagrangian, and each field satisfies appropriate field equations that follow from the Euler-Lagrange equations applied to the Lagrangian. Interactions are determined by interaction Lagrangians, that involve two or more fie

QPD processes,g Feynman diagrams, writing down the amplitudes for these diagrams and identifying the transition probabilities for specific processes. Emphasis is also placed on examples where plasma effects play a role, such that the QPD theory differs significantly from QED in vacuo. For example, this distinctio
