Description

Flat bands in twisted graphene systems offers plethora of strongly correlated states, among these, correlated insulator, superconductor and chern insulator are to name of few. Twisted trilayer graphene has shown robust superconductivity which drastically deviates from conventional weak-coupling BCS type superconductivity. In particular, twisted trilayer graphene may even host pragmatic example of strong coupling superconductivity – BEC type superconductivity. A full understanding of such superconductivity still needs more experimental works.

In this talk, I will present our transport data of magic angle twisted trilayer graphene and highlight its unconventional nature.
