We derive the ion acoustic wave dispersion relation for a linearized fluid description of a plasma with electrons and ion species. We write each quantity as X = X 0 + δ ⋅ X 1 {\displaystyle X=X_{0}+\delta \cdot X_{1}} where subscript 0 denotes the "zero-order" constant equilibrium value, and 1 denotes the first-order perturbation.

2021-03-03 · Still, high-DM FRBs are most likely luminous and distant, thus crucial for extending the dispersion–fluence relation. For example, the source with the highest DM ~2600 pc cm −3 (Bhandari et al. 2018 ; Caleb et al. 2018 ) detected thus far, FRB 160102, can be inferred to have an upper-limit of redshift z ~ 3 (Zhang 2018 ). The Green's function of a single pi meson is obtained by the method of dispersion relation utilizing the analytic and unitary properties of the nucleon- antinucleon scattering amplitude.

For brevity, we shall not treat here the derivation of dispersion relations in the framework of nonrelativistic potential theory. Concerning the latter, the interested reader can refer to the book by Nussenzweig (1972). A collection of old basic papers on field-theoretical dispersion relations can be found in the review book edited by Klein (1961).

Introduction [2] A dispersion relation is the single most important formula to characterize a wave in that it allows most of the important properties of a wave to be calculated, such as phase velocity, group velocity, and refraction.
