Query: Continuous-time hybridization expansion quantum impurity solver for
  multi-orbital systems with complex hybridizations   We describe an open-source implementation of the continuous-time
hybridization-expansion quantum Monte Carlo method for impurity models with
general instantaneous two-body interactions and complex hybridization
functions. The code is built on the ALPS libraries (Applications and Libraries
for Physics Simulations).
