Ground state phase diagram of the repulsive fermionic $t-t^{\prime}$ Hubbard model on the square lattice from weak-coupling

Phys. Rev. B 94, 085106 (2016) We obtain a complete and exact in the weak-coupling limit ($U \rightarrow 0$) ground state phase diagram of the repulsive fermionic Hubbard model on the square lattice for filling factors $0 < n < 2$ and next-nearest-neighbour hopping amplitudes $0 \le t^{\prime}...
