What are the Debye model`s assumptions for heat capacity or density of states? According to the einstein model we assume that N oscillators of the same frequency [ω][/o] and in one dimention. In three dimention N is replaced by 3N, there being three modes per oscillator.

the Deybe model assumes the same as Einstein's except that the frequency of oscillations is not a single w but a distribution from phase space.
