Research Interests

Professor Petr Stepanov is a member of the Condensed Matter Physics group at University of Notre Dame and the Stavropoulos Center for Complex Quantum Matter. He uses two-dimensional materials for studying emergent quantum phenomena with multiple experimental approaches including microscopic high-quality 2D crystal assembly, cryogenic near-field microscopy and quantum electronic transport.

Professor Stepanov’s research highlights include:

  • 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 crystal symmetry breaking in moiré electronic flat bands.
  • Revealing 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.
