In the Einstein model, all of the modes have the same frequency ω_{0}. The density of states is a delta function D(ω) = 3nδ(ω  ω_{0}). Here n is the density of atoms.
The form below generates a table of where the first column is the angular frequency ω in rad/s and the second column is the density of states D(ω) in units of s/(rad m³). The delta function is approximated by a square pulse that is ω_{0}/1000 wide.

The density of states can be used to calculate the temperature dependence of thermodynamic quantities.
