We will develop the diagrammatic Monte Carlo (DiagMC) code for solution of extended Hubbard model in the dual space, which allows to obtain an exact description of collective excitation of strongly correlated systems. We will implement a very simple and extremely efficient TRILEX2 extension of the Dual Boson code, which can be efficiently parallelized. This new computational scheme will be applied for new quantum phases of realistic materials.
