Superconductor to Insulator Transition in Twisted Trilayer Graphene
The discovery of correlated phases in twisted graphene layers has opened new avenues for exploring the physics of two dimensional electron systems. I will highlight experiments probing the emergence of superconductivity in twisted graphene tri-layers and their relation to long standing questions about the nature of superconductivity in two dimensions. Our findings include the observation of a magnetically driven superconductor to Bose insulator transition occurring at the quantum pair resistance and characterized by a scaling exponent that places trilayer graphene in the same universality class as the cuprate superconductors. Our studies of the vortex dynamics in this system revealed pinning barriers that are more than an order of magnitude lower than in any other material, making this the cleanest known superconductor.

The discovery of topologically non-trivial materials has shaped much of recent research in condensed matter physics.

In particular, the interplay of topology with magnetism and superconductivity has enabled advances that have both fundamental and practical implications. The conference will bring together leading researchers working on these topics and will be broadcast online to allow world-wide participation.
