Authors

This continuous-time hybridization-expansion solver has been written by P. Seth, I. Krivenko, M. Ferrero and O. Parcollet. It is based on a hybridization expansion of the partition function as described in references [2], [3] with implementation improvements suggested in [4].

The implementation of the two-particle Green’s function measurements contains significant contributions from L. Boehnke ([5], [6]) and H. U.R. Strand.

Release v2.1 was authored by H. U.R. Strand, for new features see the changelog.
