Waveguide QED & Quantum Networks — IAMS, Academia Sinica

Role: Research Assistant (Advisor: Hsiang-Hua Jen) · Jul 2025 – Present

Focus: Dicke-state generation, spectral analysis, and non-equilibrium effects in waveguide/cavity QED (e.g., Quantum Batteries, Quantum Mpemba Effect).

Methods: Theoretical modeling and numerics in Julia (QuantumOptics.jl) and Python (QuTiP); weekly group meetings.

Analyzed excitation dynamics and directionality in structured emitter arrays.
Explored Liouvillian spectra and relaxation pathways relevant to metrology-style enhancements.

Reciprocal Forces in Driven Granular Systems — IOP, Academia Sinica

Role: Research Assistant (Advisor: Kiwing To) · Aug 2024 – Present

Focus: Experimental characterization of reciprocal interactions; continuation with LAMMPS simulations and manuscript preparation.

Contributions: Custom Linux shell workflows for data processing; maintained analysis after PI’s retirement.
