High Temperature Superconductors can transport charge carriers with zero loss. This offers a whole new variety of possibilities, e.g. efficient transport of electric energy or creation of strong magnetic fields (fusion experiments and applications in medicine).

However, the way the transport of charge carriers happens is still unknown.

For the simulation of HTSC the complex material structure has to be described by a simple yet suffiently rich model, the Hubbard model, which accounts for the strong correlations in the materials.

In the last years, a new solver for the Hubbard model has been introduced. It combines the capacities of the variational cluster approach (VCA) with the additional degrees of freedom for the simulated particles offered by the inclusion of bath sites.

The results already obtained using the VCA show, that the inclusion of bath sites will certainly improve the results also for bilayer and multilayer systems.
