Description
Moiré materials built on transition metal dichalcogenide semiconductors have emerged as a programmable Hubbard model system. A natural question then arises: can such a system yield high-temperature superconductivity? In this talk, I will discuss the emergence of effectively high-temperature superconductivity near Mott transitions in twisted WSe2 with intermediate interaction strength. Remarkably, the emergent doping-temperature phase diagram resembles that in copper oxide superconductors. I will also discuss the evolution of the phase diagram as a function of gate-tuned displacement field that modifies the electronic band structure. The results could provide a new angle for understanding the phenomenon of high-temperature superconductivity in strongly correlated materials.
