Research Areas:
  • condensed matter physics (experimental)
  • atomic, molecular and optical physics (experimental)
  • nanoscience and nanotechnology
Research Interests:

My lab exploits quantum physics to manipulate electrons, atoms, spins and photons in various materials and artificial systems, with the aim to uncover novel quantum phenomena and new states of matter, and to explore applications in quantum devices (such as quantum information and quantum computation devices) and nanotechnology (such as nanoelectronics and nanosensors).

Research interests include:
  • graphene and 2D materials
  • topological insulators, topological superconductivity and other topological materials/quantum states
  • spintronics
  • quantum photonics
  • atomic Bose-Einstein condensates (BEC), with synthetic gauge fields and spin-orbit coupling
  • laser manipulation of atoms and molecules, cold atoms, molecules and spectroscopy
