Dr Wang Yao (University of Hong Kong)
Hybrid exciton in moiré superlattices of two-dimensional semiconductors inherits the electric dipole and strong moiré trapping from its interlayer component, whereas the local stacking registries at the trapping sites determine its intralayer component to have either an s-wave or a p-wave envelope function, MoTe2 moire bilayer being an example for the latter. This talk will explore the...

Flat electronic bands enhance electron–electron interactions and provide a platform for correlated quantum phenomena. We present two complementary approaches to engineering flat bands in graphene. In bulk alternating twisted graphene spirals, photon-energy-dependent angle-resolved photoemission spectroscopy reveals in-plane band flattening at discrete out-of-plane “magic momenta.” These...

Dr Wei Yang (Chinese Academy of Sciences (IOP-CAS))
Moiré superlattices have been demonstrated as an ideal platform for investigating novel superconductivity and topological phases in the flatband limit. In this talk, I will mainly present two complementary experiments to demonstrate the importance of the quantum metric and quantum phase fluctuations in stabilizing flatband superconductivity in alternating twisted graphene multilayers. I will...
