Here. we investigate the fractal-lattice Hubbard model using various numerical methods: exact diagonalization. the self-consistent diagonalization of a (mean-field) Hartree-Fock Hamiltonian and state-of-the-art Auxiliary-Field Quantum Monte Carlo. We focus on the Sierpinski triangle with Hausdorff dimension $1. https://www.alarecre.com/Music-Is-Freedom-Google-Pixel-7-Pro-Skin-p67850/
