Worked on the EZoni/WarpX repository to enhance the stability and accuracy of Gaussian laser initialization, particularly under complex spatial and angular chirp conditions. Addressed a critical bug in the stretch factor calculation by reverting a previous change, thereby restoring correct initialization behavior while maintaining single-precision performance benefits. Focused on improving simulation reliability and reducing the risk of errors in laser-plasma simulations, the work emphasized robust debugging and code maintenance practices. Utilized C++ and applied expertise in code refactoring, numerical methods, and physics simulation to ensure more accurate and dependable results, with all changes clearly documented and traceable within the codebase.
