Superconductivity in Bernal Bilayer Graphene Enhanced by Spin-Orbit Coupling*

Induced spin-orbit coupling (SOC) in Bernal Bilayer Graphene (BLG) placed on top of monolayer tungsten diselenide (WSe2) drastically changes its phase diagram. Most prominently, the SOC stabilizes the superconductivity in the system over a broad region of parameter space and increases the critical temperature by an order of magnitude. In this talk, I will review our recent experiments on this platform, where we tuned SOC by controlling the BLG-WSe2 twist angle and, besides superconductivity, looked into more subtle changes in the electronic phase diagram obtained by a combination of transport and capacitance measurements as well as theoretical modeling. We will also discuss the nature of the superconducting parent phase in the context of spin-valley-mixed states and our observations.
