Nodal nematic superconductivity in moir\'e graphene

Unconventional superconductivity can emerge in various forms in strongly correlated systems. Historically, the most extensively studied examples include nodal and triplet pairing, which were experimentally detected in cuprates and superfluid helium-3, respectively. Beyond these canonical cases, there are also nematic s...

Extended strange metal and superconductivity in partially filled moir\'e Hubbard bands

Moir\'e semiconductors provide a physical realization of the Hubbard model. Bandwidth-tuned Mott transitions and complex phase diagrams mimicking those of high-temperature superconductors have been demonstrated near a weak Mott insulating state at half-band-filling. The platform also provides an opportunity to explore...

Observation of Kondo Effect in Rhombohedral Graphene Superlattices

Kondo effect in strongly correlated systems arises from the antiferromagnetic coupling between itinerant conduction electrons and localized magnetic moments, giving rise to a variety of exotic quantum phenomena. Two-dimensional moir\'e superlattice systems provide a highly tunable platform featuring topological flat ba...
