I have been trying to find a way to compute the Kubo conductivity for bosons in a one-dimensional random potential analytically in continuous space. It is not an easy problem to do so because of the presence of a random potential. We have done this already using numerical techniques, but the challenge now is to find an analytical description to compare our numerical results with. Is there anyone out there who may have done this? Any help, whether directly or by reference to an article or book is greatly appreciated.
