References for non-vacuum dispersion relations

In summary, the conversation discusses the search for references on dispersion relations in generic mediums, specifically for photons and electrons. The Jackson EM textbook is recommended for a general understanding, while a textbook on Plasma Physics is suggested for a more in-depth derivation. However, it is noted that dispersion relations are affected by various factors and there is no one generic medium.

Hi guys,

I'm looking for some references where dispersion relations, say for photons, are explicitely written out in a generic medium. In other words, the dispersion relation for particles not propagating in the vacuum is a different one than the standard vacuum one [tex]E^2 = p^2 + m^2[/tex] and I'm looking for papers/books where such relations are written out. Possibly for the photon or for electrons. Do you know any?

The Jackson EM textbook covers that and is very valuable for most aspects of EM with a bit of a bridge into QM and relativity. If you really want to dig into dispersion and see a full derivation you may want to look at a textbook on Plasma Physics such as Introduction to Plasma Physics: With Space and Laboratory Applications by D. A. Gurnett and A. Bhattacharjee. But that will require a working understanding of the Maxwell Equations and the Fourier Transform.

But unfortunately there is no generic medium. Molecular/atomic/ionic densities, particle trajectories, temperature and presence of EM fields, for example, all profoundly affect dispersion relations.

Related to References for non-vacuum dispersion relations

1. What are "non-vacuum dispersion relations"?

Non-vacuum dispersion relations are mathematical equations that describe the relationship between the wavelength or frequency of electromagnetic radiation and the refractive index of a material, in a medium other than a vacuum. These equations help us understand how light behaves in different materials and can be used to design and optimize optical systems.

2. How do non-vacuum dispersion relations differ from vacuum dispersion relations?

Vacuum dispersion relations describe the behavior of light in a vacuum, where there are no particles to interact with the electromagnetic waves. Non-vacuum dispersion relations take into account the effect of the medium on the propagation of light, which can cause changes in the speed and direction of the waves.

3. What types of materials are described by non-vacuum dispersion relations?

Non-vacuum dispersion relations can be applied to a wide range of materials, including liquids, gases, and solids. These equations are particularly useful for understanding the behavior of light in transparent materials, such as glass, water, and air.

4. How are non-vacuum dispersion relations calculated?

Non-vacuum dispersion relations are calculated by combining experimental data with theoretical models that describe the interaction between light and matter. These models take into account the material's optical properties, such as its refractive index, absorption coefficient, and scattering properties, to predict the behavior of light in that material.

5. What are some practical applications of non-vacuum dispersion relations?

Non-vacuum dispersion relations have numerous practical applications, such as in the design of optical sensors, lenses, and other optical components. They are also used in spectroscopy and remote sensing to analyze the composition of materials. Additionally, non-vacuum dispersion relations play a crucial role in understanding the properties of light in biological systems, such as the human eye.
