The Shastry–Sutherland model provides an effective description of the layered material SrCu₂(BO₃)₂, which exhibits a very rich phase diagram as a function of pressure and magnetic field. In this talk, I will discuss recent progress in the numerical study of this system using infinite projected entangled-pair states (iPEPS), a tensor network ansatz for representing quantum states directly in the 2D thermodynamic limit. I will show how iPEPS has provided new insights into the fascinating properties of SrCu₂(BO₃)₂, including its intriguing sequence of magnetization plateaus, supersolid phases, and a finite-temperature critical point. Finally, I will present recent high-precision iPEPS results that reveal a narrow quantum spin liquid phase between the plaquette and antiferromagnetic phases
