Magnetism and Mottness in the anisotropic triangular lattice Hubbard model: a cellular dynamical mean-field study — •Marcel Klett¹, Henri Menke², Michel Ferrero³, Antoine Georges³, and Thomas Schäfer¹ — ¹Max Planck Institute for Solid State Research, Stuttgart, Germany — ²University of Erlangen-Nuremberg, Erlangen, Germany — ³College de France, Paris, France

We investigate the phase diagram of the anisotropic triangular lattice Hubbard model in a center-focused cellular dynamical mean-field theory (CDMFT) approach using an impurity with 7 sites. We investigate the Mott metal-to-insulator transition and crossover region as well as the superconducting phase. Using a spin symmetry-broken approach of the CDMFT, allowing for a rotations of spins on the Bloch sphere, we are able to investigate the magnetic ordering of the different cluster schemes.
