Two-particle Response

This Tutorial Series to teaches you various aspects on two-particle response calculations. You can find the associated Jupyter Notebooks in the TwoParticleResponse subdirectory of the TRIQS/tutorials.

• Fermions on the square lattice & perfect nesting
• Susceptibility \(\chi_0\) of non-interacting fermions
• The random phase approximation (RPA)
• Two-particle self consistency (TPSC)
• Finite temperature antiferromagnetism in two dimensional systems
