The free electron gas found in metals is a very good conductor of heat and dominates thermal conductivity.
If the temperature is extremely low, the behavior of the electrons comes close to the quantum mechanical model of a free electron gas.
Many quantum phase transitions in two-dimensional electron gases belong to this class.
The weakly interacting regime of densities is known as the electron gas.
Thus the high-density regime is known as an electron gas.
White dwarf stars are supported by the degeneracy pressure of the electron gas in their interior.
For applications of this integral see Magnetic interaction between current loops in a simple plasma or electron gas.
The oscillations can be described as an instability in the dielectric function of a free electron gas.
"It is an organized form of electron gas."
The most successful approach is based on the homogeneous electron gas.
