๐ Ph.D. candidate at Peking University, majoring in Nuclear Technology and Applications
๐ฌ Researcher in THz science, plasma physics, and high-performance computing
๐ป Developer in scientific simulation and AI-aligned software tools
I'm passionate about combining physics, computation, and system design to explore fundamental science and build impactful tools. My current research focuses on:
- Terahertz quantum optics & structured light
- Relativistic laser-plasma interactions
- HPC-driven simulation & parallel computing
Iโve contributed to both theoretical modeling and large-scale simulation tools using frameworks like WarpX, Smilei, and AMReX. My code enables high-precision modeling of THz polarization, spin dynamics, and photonic transport in plasma-based environments.
Languages: C++, Python, Bash, JavaScript
Frameworks: AMReX, Smilei, WarpX, Pybind11, FastAPI, React
HPC Tools: MPI, CUDA, CMake, Git
Fields: Plasma physics, THz optics, vector light, parallel computation, digital signal/image processing
- ๐ WarpX/Smilei THz Modules: Developed focused beam and spin tracking modules; enabled 20x speedup in THz propagation simulations.
- ๐ฐ๏ธ FarRadio_cmake: Modular radiation analysis tool based on retarded potential theory; supports spin and phase extraction in time domain.
- ๐ฅ Camera System: Built backend/frontend for femtosecond pulse diagnostics via high-speed camera data streaming.
- Optics Letters (2022): Collimated THz pulses from cone-target transition radiation
- High Power Laser Science and Engineering (2023): Frequency-tunable THz from plasma wiggler
- Chinese Physics B (2025): Broadband THz generation via photon deceleration
- (More under submission...)
