CORE DIRECTION
Orbital and Valley Transport
Theory of orbital and valley transport, including orbital Hall physics, orbital magnetic moments, nonconserved accumulations, and Hanle-type dynamics.
My research spans condensed-matter theory and quantum science, with an emphasis on experimentally relevant transport, geometry, and many-body phenomena.
CORE DIRECTION
Moiré and Supermoiré Quantum Materials
Moiré and supermoiré graphene, with focus on magnetic Bloch states, Hofstadter physics, Brown–Zak oscillations, and multiscale commensurability.
BRIDGE
Quantum Geometry and Nonequilibrium Responses
Berry curvature, quantum geometry, and orbital magnetic moments in electronic, magnetic, optical, and nonequilibrium response.
EMERGING DIRECTION
Atomic Many-Body Physics and Neutral-Atom Quantum Science
High-precision atomic many-body theory for Rydberg atoms and neutral-atom platforms, using relativistic coupled-cluster and CI+MBPT methods.
Approach
I combine analytical theory and numerical modeling across several complementary scales, choosing the method according to the physical question and the experimentally accessible observable.
- Linear-response, semiclassical, and Green's-function methods for quantum transport and response
- Tight-binding and continuum models for low-dimensional and moiré quantum materials
- Many-body perturbation and Hartree–Fock-based approaches for interaction-driven phenomena
- Density-functional and first-principles calculations where microscopic electronic structure is essential
- Relativistic coupled-cluster and CI+MBPT methods for high-precision atomic structure and Rydberg physics
