Quantitative evaluation?
ehrenfest said:What? I mean I don't understand why it is true. It is also on page 142 of Kittel.
malawi_glenn said:Oki I just mean the eq under that headline.
What is the fermi dirac distribution at T = 0K? well f (T goes to 0) = 1.. (see eq 5 p.136 and take limit t goes to 0).
malawi_glenn said:Oh yes, it meant when kT << E_f
:)

Condensed matter-integral over density of states is a concept in condensed matter physics that describes the total number of allowed energy states in a material or system. It is often represented as a function of energy and is used to study the electronic and magnetic properties of materials.
Studying condensed matter-integral over density of states is important because it allows scientists to understand the fundamental properties and behaviors of materials at the atomic and subatomic level. This information is crucial for developing new materials with specific properties and for improving existing technologies.
Condensed matter-integral over density of states is typically calculated using mathematical models and equations that take into account the energy levels and interactions between particles in a material. These calculations can also be done experimentally by measuring the energy levels of a material using techniques such as spectroscopy.
The condensed matter-integral over density of states can be affected by various factors, such as temperature, pressure, and the composition of the material. Changes in these parameters can alter the energy levels and interactions between particles, resulting in a different density of states.
Condensed matter-integral over density of states is closely related to other properties of materials, such as conductivity, magnetism, and thermal behavior. By understanding the density of states, scientists can gain insights into how these properties emerge and how they can be manipulated for practical applications.
