From: Antiferromagnetic Metal and Mott Transition on Shastry-Sutherland Lattice
T − U Phase diagram of interacting fermions on the Shastry-Sutherland Lattice at t2 = 1.0.
The black line indicates the transition from a metal to an insulator and the red line shows the transition from the paramagnetic (PM) phase to the antiferromagnetic (AFM) phase. When the temperature is low enough, with the increasing U, there exists a region of antiferromagnetic metal phase before the system enters the antiferromagnetic insulator phase. The insert picture is for the case when t2 = 1.3.
