PROFILE
Ziwei Chai
Contributed to the cp2k/cp2k repository by developing two core features over a two-month period, focusing on computational chemistry and scientific computing using Fortran. Delivered integration of Planar Countercharge and Planar Averaged Electrostatic Potential, enhancing CP2K’s ability to model planar electrostatics in complex electrochemical systems through robust input handling and Kohn-Sham integration. Subsequently implemented Pulay density mixing for grand canonical calculations, improving convergence and suppressing charge sloshing within the existing density-mixing framework. Work emphasized code extensibility, parameter configurability, and adherence to project standards, demonstrating depth in numerical methods and quantum chemistry without direct involvement in bug fixing during this period.
