Description
We investigate the phase diagram of the unfrustrated triangular lattice Hubbard model in a center-focused cellular dynamical mean-field theory (CDMFT) approach using impurity clusters of 4, 7 and 19 sites. We investigate the Mott metal-to-insulator transition and crossover region in terms of these cluster sizes. Using a magnetic 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.
