About

The TRIQS arbitrary Crossing Approximation (XCA) impurity solver has been developed by F. Rilloraza, Z. Huang, J. Kaye, and H. U.R. Strand. We thank N. Wentzell for contributions, support and guidance in using the TRIQS library and its related packages.

For compact representation of imaginary time propagators we use the C++ implementation of the Discrete Lehmann Representation provided by the cppdlr library. The TRIQS application structure is inherited from the app4triqs framework.
