Other Research-Related Contributions
🛠️ Pre-AI Technical Work (before 2022)
The following works focus on (material-specific) tight-binding (TB) models. They are adopted across both Dr. Hsin Lin and Prof. Tay-Rong Chang’s research groups. See a minimal example here.
Led the consolidation of MATLAB codes on TB models across projects into a unified framework to support consistent and maintainable development.
Established and managed the corresponding codebase through private GitHub organizations.
Designed and implemented a standardized variable and notation convention within the codebase to improve clarity, reusability, and collaboration.
🤖 AI-Enhanced Research Practice (after 2022)
Explored prompt engineering techniques for research writing using LLM.
Utilized AI-enhanced development environments (e.g., Cursor and Copilot) for research coding and side projects, including (but not limited to):
A Python script to automate sequential computations of SCF, relaxation, and BS through VASP.
A webpage tracking the manuscript status through interactive plots.
Some webpages in this web site.
📄 Unpublished Research Works
These projects were completed independently, of which I am the first author. Due to shifting research focus or publication priorities, they were not submitted for publication.
- Topic: Topological Two-Fold Fermions in Two- and Four-Dimensions
Time: 2023Description: I discovered a four-dimensional lattice model with two-fold degenerated band touchings protected by non-trivial topology.
- Topic: Valley Topology
Time: 2023Description: I analyzed a multilayer spin-valley locking system through projected spectrum. I discovered that the layer and the valley degrees of freedom are also locked in this system, and the topology carried by the valleys can thus be well-defined through projected spectrum.
- Topic: Graph Theoretical Real-Space Renormalization Group For Tight-Binding Hamiltonian
Time: 2022Description: I used lattice graph description of tight-binding Hamiltonian to prove that it is impossible to use the renormalization method to obtain the spectrum of localized states on higher-order boundaries (e.g., corners of a nanodisk or hinges of a cuboid etc.).
