Research Interests

Quantum many-body physics. Unconventional superconductivity. 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 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.
