Research Interests

Quantum many-body physics in quantum materials. Unconventional superconductivity. Hubbard physics in twisted bilayer systems. Exotic quantum Hall phases of 2D electrons.

My primary interest is to investigate and understand quantum many-body interactions in various physical systems, such as exotic quantum Hall phases of 2D electrons and unconventional topological superconductivity in layered materials.

Previously, I have used ultrasensitive phase-locked cantilever magnetometry to investigate the unique magnetic responses of the spin-triplet topological p-wave superconductivity in Sr2RuO4. As a postdoctoral fellow at MIT, I employed novel pulsed tunneling techniques to study strongly interacting 2D electronic phases in high magnetic fields (See the listed papers below for further reference). From these experiences, I would like to further extend my techniques toward spatially-resolved, quantum-enhanced sensing measurements and apply them to various materials and engineered systems that may exhibit exotic, topological quantum many-body phenomena. Some fantastic examples include the superconductivity in doped topological insulators, magnetism in quantum materials, and twisted bilayer graphene-TMDs and much more.

Will the law of physics allow us to find the unified understanding of quantum many-body phenomena and a way to control them? I think we are getting ever closer to find the answer.
