Magnetic and charge susceptibilities in the half-filled triangular lattice Hubbard model

We study the momentum-dependent magnetic and charge susceptibilities in the half-filled two-dimensional triangular Hubbard model within the ladder dual fermion approximation in the metallic, Mott insulating, and crossover regions of parameter space. In the insulating state, we find strong spin fluct...
