About
My work in theoretical condensed matter physics centers on topology, collective dynamics, and quantum information, with an emphasis on academically rigorous models that stay close to real materials and platforms. I use an analytical-plus-numerical workflow to connect first-principles theory with experimentally relevant predictions.
Current focus: building models for topological phases and magnonic platforms that clarify transport, coupling, and nonequilibrium dynamics.
Next: beginning doctoral research that unifies condensed matter theory, quantum information, and open quantum systems.
Experience highlights
- SUPREME REU at MIT (Luqiao Liu): magnonic spin-wave simulations, cavity-magnon coupling, and parametric down-conversion.
- Topological Condensed Matter Theory (Junyeong Ahn): Stiefel-Whitney phases, nodal-line systems, and Kubo conductivity calculations.
