We apply symmetry principles and electronic structure design to predict, engineer, and uncover emergent quantum phenomena.
We apply symmetry principles and electronic structure design to predict, engineer, and uncover emergent quantum phenomena.
Symmetry: We manipulate different symmetries to drive novel quantum responses; for example, we strategically break spatial inversion and time-reversal symmetries to realize Weyl-mediated chiral magnetism and superconducting diode effect.
Band Engineering: We target distinct features in low-energy band structures—from linearly dispersive Dirac and Weyl nodes to strong electron-phonon coupling for quantum transport.
Interfacial Engineering and Physical Modeling: By coupling distinct materials across functional heterostructures, we create emergent interfacial properties and develop analytical models to understand and optimize device performance.
Synthesis & Fabrication
Synthesis & Fabrication
To translate design principles into physical reality, we combine material synthesis and nanofabrication across length scales—from bulk crystals down to single atomic layers—to engineer atomically pristine interfaces that enable strong quantum coupling.

Single Crystal & Thin Film Growth: We synthesize high-purity single crystals and epitaxial thin films to tailor structural and electronic ground states.
Nanofabrication: We employ state-of-the-art lithography, etching, and deposition tools to pattern mesoscopic devices, where we probe subtle quantum transport signatures.
2D Heterostructures: We utilize dry-transfer techniques to assemble 2D van der Waals layers with atomic-scale precision. For example, in our Fe(Te,Se) van der Waals Josephson junctions, an intact atomic lattice across a ~4 Å barrier enables coherent supercurrent tunneling between topological superconductors without degradation.

Quantum & Mesoscopic Electron Transport: We perform low-temperature, high-magnetic-field, and gate-tunable measurements to detect signatures of topological phases and unconventional superconducting properties.
Structure & Morphology: To build accurate structure-property relationships, we employ benchtop and facility tools to verify crystal quality, surface topography, and stoichiometry.
Multimodal Probes: To resolve spatial inhomogeneity and local order, we actively collaborate with specialists in complementary techniques, such as nitrogen-vacancy (NV) center magnetometry and ultrafast optical spectroscopy.
