The rotor is on so tight I couldn... Brake question 1 answer My sons car is having issues with the brakes.
Fermi-Dirac distribution function. (statistical mechanics). A function specifying the probability that a member of an assembly of independent fermions, such as electrons in a semiconductor or metal, will occupy a certain energy state when thermal equilibrium exists.
The Lindhard function of free electron gas is so elementary that its closed form can be obtained in clarity. Despite its simplicity, some nontrivial physics manifest. In 1D, the divergence of static response function ($\omega=0$) indicates the well known Peierls instability and the system tends to break its translational symmetry.
