Spin and charge density waves in the Lieb lattice
J. D. Gouveia, R. G. Dias
We study the mean-field phase diagram of the two-dimensional (2D) Hubbard model in the Lieb lattice allowing for spin and charge density waves. Previous studies of this diagram hav…

Magnetic phase diagram of the Hubbard model in the Lieb lattice
J. D. Gouveia, R. G. Dias
We study the mean-field phase diagram of the repulsive Hubbard model in the Lieb lattice. Far from half-filling, the most stable phases are paramagnetism for low on-site interactio…
