Dear Mr Troyer,
thank you for the help. I'm going to edit the file and I'll write to you
soon to let you know if the program works properly.
Thank you again for the help,
best regards

Dear Matthias or all users community,
As is said in the tile, I have a problem about running python. It is
that when I type "impot pyalps" and "import pyalps.plot", it appears
on the screen that "ImportError: No module named scipy ". And I have
no idea about that. Does anyone help,please? Thanks.

Dear Hunter,
in your email you asked how to address the noise in the tail of the self-energy in the hybridization expansion CTQMC. We have recently addressed exactly this problem. A preprint is now available at http://arxiv.org/abs/1108.1936. We are implementing this into the code in the SVN, so that it will eventually be available in a future release of ALPS.
Best regards,
Hartmut

I suppose it is not surprising that subtracting the inverses of two small numbers would lead to this sort of thing.

For the forward transform, these seem to be boundary terms in a numerical integration-by-parts method. They also appear in the backward transform, although it is less clear to me what their function might be. I was also wondering, if it does not exceed the scope of a mailing list query, if there are other places in the provided dmft code in which the Bethe lattice is tacitly assumed.
