1) For a d-dimensional medium in which the lowest-lying vibrational modes of wavelength A have frequencies given by a dispersion relation of the form w ~ A-8, find expressions for the internal energy and the specific heat at constant volume using the Debye approximation. What is the behaviour of Cy (T) near absolute zero?
