Microscopic description of glass-light interaction

In summary, the conversation is about the request for references on how to describe the microscopic interaction of light with disordered systems, specifically glass. The suggested models to consider for a disordered system are discussed, as well as the explanation of the permittivity or permeability curve vs frequency of the external field. The article "The theory and properties of randomly disordered crystals and related physical systems" and the book by Economou are recommended as good starting points for this topic.

Hi all,
could you suggest me references that can help me in the following calculation?
I would like to see how to describe microscopically the interaction of light (or in general of an external field) with a disordered system such as glass ( I can find literature only for materials modeled with regular lattices). Could you suggest which model has to be considered for a disordered system?
To be concrete: how can microscopically 'explain' the curve permittivity or permeability vs frequancy of the external field (light) for a glass?

Thanks in advance!

I think this article is a good starting point:

@article{RevModPhys.46.465,
title = {The theory and properties of randomly disordered crystals and related physical systems},
author = {Elliott, R. J. and Krumhansl, J. A. and Leath, P. L.},
journal = {Rev. Mod. Phys.},
volume = {46},
issue = {3},
pages = {465--543},
numpages = {0},
year = {1974},
month = {Jul},
publisher = {American Physical Society},
doi = {10.1103/RevModPhys.46.465},
url = {http://link.aps.org/doi/10.1103/RevModPhys.46.465}
}

Also the book by Economou treats disordered systems:

1. What is the microscopic description of glass-light interaction?

The microscopic description of glass-light interaction is the study of how light behaves when it passes through or interacts with glass at a microscopic level. This includes the reflection, refraction, absorption, and transmission of light through different types of glass.

2. How does glass affect the color of light passing through it?

Glass can affect the color of light passing through it in several ways. It can absorb certain wavelengths of light, making the light that passes through it appear a different color. It can also cause dispersion, where different wavelengths of light are refracted at different angles, leading to a separation of colors.

3. What is the role of the glass structure in light interaction?

The structure of glass plays a crucial role in light interaction. The arrangement of molecules in glass determines how light will pass through it, which affects the overall appearance and properties of the glass. For example, the presence of impurities or defects in the glass structure can alter the way light interacts with it.

4. How does the thickness of glass affect light interaction?

The thickness of glass can have a significant impact on light interaction. Thicker glass can absorb more light, resulting in less transmission. It can also cause more refraction and dispersion of light, leading to a distorted or colored appearance. In contrast, thinner glass allows more light to pass through and may have less of an effect on the color of light.

5. What techniques are used to study the microscopic description of glass-light interaction?

There are several techniques used to study the microscopic description of glass-light interaction, including spectroscopy, microscopy, and computational methods. Spectroscopy involves using light to measure the properties of glass, such as its absorption and transmission spectra. Microscopy allows for the visualization of the structure and behavior of glass at a microscopic level. Computational methods use mathematical models and simulations to understand the interaction of light with glass and predict its behavior.
