With Peter Petrov of Imperial College London, we explored the pi plasmons (these are important for understanding the bonding state of interfaces) in the Topological Insulator Bi2Se3 when it is interfaced with graphene.

This is an important system to understand because graphene is used to encapsulate Bi2Se3 for applications in quantum technology. Our publication in Scientific Reports is available at:
