We use two-dimensional materials to study emergent quantum phenomena with multiple experimental approaches, including microscopic high-quality 2D crystal assembly, cryogenic near-field microscopy and quantum transport. Broadly defined, we are interested in the following topics:
- Manipulation of strong electronic interactions in graphene-based moiré materials.
- Local photocurrent studies of strongly correlated phenomena in magic angle twisted bi/trilayer graphene heterostructures.
- Plasmon polaritons in strongly correlated environment.
- Studies of time-reversal and inversion symmetry breaking in moiré electronic flat bands.
- Revealing coexisting superconductors and orbital ferromagnetic states in the same moiré device for further studies of exotic quantum phenomena.
- Studies of pure spin transport in graphene antiferromagnetic insulators.
- Quantum Hall effect in multi-Dirac band electronic systems.
