Hello !
This is the source code for an impurity solver based on the Non-Crossing Approximation, as part of the TRIQS project: https://github.com/TRIQS/triqs. It requires the 2.1.x version.
This project was achieved together with Francesco Peronaci, Antoine Georges, Michel Ferrero and Olivier Parcollet. Details are available in my PhD manuscript: https://theses.fr/2020IPPAX026 Three different branches are available:
- the full out-of-equilibrium solver (master), where the use of the solve equilibrium method can be specified
- the two-branch method based on Keldysh formalism (two_branches)
- the steady-state method (ness) that uses the long-time limit of the equations
This code was developed during my PhD under the supervision of Antoine Georges and Michel Ferrero, at Collège de France (Paris), Ecole polytechnique (Palaiseau) and Flatiron Institute (New York). Note that the code is not maintained anymore.
